  1. so here is the thread, Ill start from my personal experience Ive never had a problem with it and my following comments are based on using it myself, not here say. I know for a fact it doesnt make fish infertile at all...Just makes the females colour up and look like males so kinda confuses the fish and can make breeding a little more difficult. when I was a noob and first got into keeping africans 5-6 years ago, I had one 4ft display tank full of e-blues, I wanted them looking as blue as possible so I had them on a 50/50 mix of protein pellets and white crane. The intense blue they all turned was friken amazing. I had them all for around 3 years on that same diet with no apparant ill effects. They were even breeding even though they all looked like males, and I wasnt even trying to breed them as I only had the one tank at that time and had no idea about breeding a rearing fry etc... Unfortunately I lost the lot during a summer heatwave. Some people are dead against it, and if your breeding fish I can understand why, but for a display tank to get the most colour out of your fish imo I cant see a reason to not use it. After losing all the eblues I went to an african community tank and there diet fed was primarily white crane...this tank was kept this way untill I moved houses so was a good 3 years, and again had no problems with fish health. Im not for or against using white crane but from my experience of using it havent seen any negative effects on fish fed it. If someones got some info, from a study with proof that it is detrimental to the fishes health in any way Id like to read it....
  2. All the threads are raised for the fish that members have elected to work with as our named projects. Altolamprologus compressiceps "Muzi" Boulenger, 1898 Betta macrostoma Regan, 1910 Gymnogeophagus balzanii Perugia, 1981 Cynotilapia sp. 'hara' Not yet described Neolamprologus kungweensis Poll, 1956 Metriaclima sp. 'zebra gold' "Charo" Not yet described Cynotilapia zebroides "Chewere" Johnson, 1975 Cynotilapia zebroides "Cobue" Johnson, 1975 Metriaclima pulpican Tawil, 2002 The first challenge is sourcing fish, and preferably fish from different lines, and then ensuring that our practices are producing quality, maybe by trading spare males, maybe swapping fry. I thought I would raise this as some members have had some interesting things to say to me about hwo to approach this project. This is a member driven project so I thought we could allow this section for a general discussion of ways to progress and ideas. Steve
  3. Hi guys I've been thinking about this for a while and i am posting this thread to see what suggestions everyone has of heaters, pumps etc for saving as much electricity they can but at the same time still powerful enough for your likings. I will be setting up some 2fts and want to upgrade all my heaters and air pump. I want to be using jäger heaters but not sure if I should get 100w heaters and wanting info to explain how it works with the watts to save? All suggestions and info please post.
  4. Sima and the mislabeled Xenotilapia Ornatipinnis Moliro Firestream are indeed the same fish The firestreams are not actually Ornatipinnis, they are Sima... but also the species which was originally brought into Australia as the Sima was later revised and changed to X. Boulengeri Where was the X. Ornatipinnis are the very rare and I am yet to meet someone else with them. - Thomas Anderson - The Cichlid Room Companion There was a discussion about this between a few overseas people and it seems the confusion is not only in Australia... but with education, it can help reduce that confusion.
  5. To continue discussion from another thread (found here Fry that arent selling): You are correct that you don't have to agree with certain reclassifications. The entire process can be quite political, just look at the Metriaclima/Maylandia debate. Having said that, more often then not a description or reclassification with supporting evidence will be accepted. If you ever want to view the evidence for yourself, it is available to you. In the case of the reclassification of Pseudotropheus cyaneorhabdos, the relevant articles are as follows: Original description of "Melanochromis" Trewavas, Ethelwynn. 1935. "A Synopsis of the Cichlid Fishes of Lake Nyasa". Annals and Magazine of Natural History. Series 10; pp. 65-118 Original descrition of "Pseudotropheus" Regan, Charles Tate. 1922. "The Classification of the Fishes of the Family Cichlidae.--II. On African and Syrian Genera Not Restricted to the Great Lakes". Annals and Magazine of Natural History. v. 9(n. 10), p 252 Original description of "Melanochromis cyaneorhabdos" Bowers, Nancy & J. Stauffer. 1997. "Eight new species of rock-dwelling cichlids of the genus Melanochromis (Teleostei: Cichlidae) from Lake Malawi, Africa". Ichthyological Explorations of Freshwaters. v. 8 (1); pp. 49-70 Reclassification of "Pseudotropheus cyaneorhabdos" Tawil, Patrick. 2002. "Notes sur le genre Melanochromis et l'appartenance générique de Pseudotropheus johannii Eccles, 1973, et espèces apparentées". L'an Cichlidé. v. 2; pp. 61-68 Before you ask DFF, no I have not reviewed all of these documents myself. I have faith in the experts to deal with these issues until such time as I am suitably qualified to do so myself. I believe there is no required qualifications to describe or reclassify species; it is a matter of publishing an article in accordance with the relevant codes in a peer reviewed journal. If your article is accepted by your "peers" (other biologists and ichthyologists) then it becomes official. It will always be difficult to break old habits, but if we don't start now and proactively use the (currently) correct names ourselves, the greater community will continue to live in the past. On the difference between Pseudotropheus and Melanochromis: Pseudotropheus is distinguished from Melanochromis by the absence of a reversion of the melanin pattern in dominant individuals (Tawil, 2002b; Konings-Dudin et al., 2009). My comments on this matter: My general feeling is that Pseudotropheus cyaneorhabdos was reclassified, not so much because it closer resembles Pseudotropheus, but because it excludes itself from being classified as Melanochromis. I would not be surprised to see it reclassified into a newly erected genus at some point in the future. Ok go!
  6. Article: http://www.qldaf.com/forums/articles-species-catalogue-70/care-breeding-electric-blue-jack-dempsey-70469/#post456688 Please discuss my article on EBJD on this thread. Happy to discuss or answer any further q's.
  7. Ok I like so meany use rain water to do my water changes .I however have no town water to my property and rely on rain 100% yes I can buy it in but it's not cheap .all my fish are breeding and growing and healthy so no problem there .as I run coral in a lot of my tanks and add salt .so hear is my ? How do you guys buffer you water up ? Salt ? How much ? Which one ?( sea salt,marine salt ,Epsom salt .) or cichlid buffer which will cost a fortune doing 8-10 thousand L system . My tank water is 5.6 ph and carben hardness is 0 ppm And tank is ph7.8 and carben hardness 20 ppm Any thorts? Or tips Thanks Steve
  8. ok there is allways a thread on a sump somewhere and the good ole bioball comes up in discussion as to whether they should be submerged or not. This thread is here to discuss what they are used for and where they should be used... Ill go first with my understanding but would invite anyone to correct me if I am wrong.... ok, from my understanding of the whole process, and Ill keep it as basic as possible, Yes you can submerge them, and they will house anearobic bacteria, but they are not as efficient as other media such as matrix, scoria or coral rubble etc... Preferably, when bioballs are used in a wet dry sump, in the dry trickle section, they are there to house aerobic bacteria, and many would be led to beleive that this bacteria is de-nitrifying? yes?... well no, since denitrifying bacteria will only thrive in low to no dissolved oxygen and low water flow environments..... how can they survive when the top section of the sump where the bioballs are is saturated with dissolved oxygen from falling water from the tank, well, they cant really can they? so in saying that, youd think the common trickle filter sump setup would be a waist of time then, yes?.... NO! the nitrate is being removed BEFORE it is even formed....huh...how you say? well, ammonia is a gas, but will dissolve when in water but it prefers to be a gas. A good amount of ammonia is removed by the falling action as the water tumbles over the bioballs. Removing ammonia before it goes through the nitrogen cycle means that less will remain to be turned into nitrate by biological filtration, leading to reduced levels of nitrate in the tank! How ever much or little nitrate is 'removed' would be hard to measure, but any nitrate removed, especially from a non planted tank, is beneficial IMO if the above were wrong the bio balls will still house beneficial bacteria, and will greatly oxygenate the water so its win win Thats my understanding from what I have read and digested over the years ....
  9. Figured I'd throw this one out there to create a stir. QLDAF currently looks down upon the breeding and distribution of hybrids, regardless of quality. The ultimate purpose of QLDAF having a negative stance on hybrids is to facilitate the maintenance of genuine species. Many of the species used by breeders to create hybrids are import restricted, and cross-breeding (deliberate or accidental) has a heavy negative effect on the lines that we're lucky enough to have present. Currently, we do not allow promotion or advertisement of the following species: - Flowerhorns & Similiar Hybrids (Typical trimaculatus/labiatus/citrinellum/synspilum hybrids) - Blood Parrots - Accidental Hybrids (Non-recognised "Backyard" Hybrids) I'm especially interested what people think about the following: - Aulonocara Hybrids (Dragon Blood/Peacock Hybrids) - Aquarium Strain Symphysodon (Discus) - Aquarium Strain Pterophyllum (Angelfish) - Electric Blue Jack Dempseys - "Marbled" V. fenestratus .. and just for the sake of it, opinions on non-hybrid: - Longfin/Balloon Varieties My opinions? I'm sticking to the opinion that "natural is beautiful": everything listed above does not appeal to me in the slightest. That sounds like a pretty good way to kick start a bias argument some might say, but that is my honest opinion. Regarding Hybrids, particularly Flowerhorns and other CA mutts, I firmly believe that regardless of the "control" some hybrid breeders pretend to take over the preservation of lines, somewhere along the line fish they have bred already have and will taint the limited lines of natural species that we can no longer import, such as Amphilophus and Vieja species. Blood Parrots simply disgust me, as they appeal primarily to the less-experienced market demographic who are more than likely unaware that they are essentially a deformed hybrid mess. I look at balloon varieties in the same light as a similar "market fad" for pawning off deformed specimens. I don't know what to think about the Discus and Angel situation. If I was to ever keep these specimens in the future, they would always be wild strain. While many of the colour morphs may technically be hybrids, Discus and Angelfish are still legal imports, allowing us to replenish natural lines. Unfortunately, I think most of the damage has already been done. I would like this thread to remain as constructive as possible. Any personal attacks that aren't above board or don't relate to the topic at hand will be simply removed. If enough people get involved we might just end up with a solid debate and consensus of what hobbyists truly think of much-argued dilemma. What are your thoughts? Edit: Just to clarify, this is not to form a ruleset. It's simply a discussion.
