  1. Cant sell or trade it, if wild caught. Needs to be legal size. Need a well cycled tank, nitrite is deadly. High pH is needed, and if you are going to salt it, keep the level consistant to prevent the biofiltration failing.
  2. Couple of theories. 1) Your dead livestock needs higher oxygen levels than your living livestock. So warmer water and less surface agitation could explain who lived and who died. Aside from just being species that need more oxygen its likely they were larger fish too, and larger fish, need more oxygen than smaller ones. 2) A CO2 misshap, as in an overdose. 3) A bacterial infection that attacks gills, could have spread through the fish. Some fish like neons are so tolerant that its hard not to just assume they are the carriers!
  3. When food gets wet...... Wet food goes moldy and can cause disease and death in fish. So, if a fish splashes water into the fish food container, immediately freeze it! This will prevent it from spoiling. I usually transfer the food into ziplock bags before putting it in the freezer.
  4. Thats a lot of medicating already. I agree it does look bacterial, or at least has a bacterial infection component to it. Priority first tho. What temperature is the aquarium? And bonus questions, Have you inspected the gill filaments on freshly dead fish to confirm columnaris? Do you have Indian Almond leaves you can use to ease the fish back into normal aquarium conditions once the medication train is complete?
  5. synspillum and peaceful are not words that usually go together lol
  6. one method of keeping Axolotls in QLD This is a huge complicated hobby, with many many different paths to success. No where does the hobby get more confused than where axo's are concerned. Even while successfully producing Axos for the pet trade, I have been constantly bombarded by people telling me I was doing it all wrong. So.... here goes nothing lol. Axolotyls come from cold highly oxygenated water, so to replicated that in QLD a chiller is required. And of course if you can add a chiller, then thats what you want to do! But, sometimes a chiller is not an option, and thats the scenario we are going to explore. Theres 3 main parts to the following strategy. 1) Aggressive aeration, with a degree of redundancy -> twin airpumps running AND a backup battery airpump for use during power outages. Aggressive aeration is needed as the warmer water cannot hold much oxygen, so we need to replace any oxygen used up by axolotl or the living microbes in filtration. Having 2 airpumps provides redundancy and means that even if one pump fails the other will keep everything alive. The battery powered aerator is insurance, and ensures that even in a disaster situation we can take care of the immediate threat to axo life. Its worth taking your time choosing the airpumps, a quiet airpump is a beautiful thing and well worth a few extra $. 2) Excessive biofiltration -> multiple mature air powered sponge filters Like every aquarium, we need to establish microbes on our biofiltration before we start adding delicate livestock. This is especially critical with axos as any gill damage from ammonia or blood damage from nitrite will only compound the difficulty of keeping axos in warmer water. I would highly recommend purchasing ammonia and nitrite test kits, these are a very useful tool when "fishless" cycling the aquarium. This is the proccess of adding fish food before adding livestock and then tracking the rise of ammonia and nitrite, and then its fall to the desired 0ppm. By taking your time and then stress testing the aquarium with fish food + ammonia/nitrite testing, we can be sure that when we introduce and start feeding our axo we are not going to get a rude ammonia/nitrite spike surprise. While air powered sponge filters are ugly.... they are perfect in almost every other way. They have no moving parts to break, are very cheap, reliable and provide excellent biofiltration and oxygenation. They are very easy to clean (always in a bucket of water taken from the aquarium they run on, to ensure we trim rather than destroy the good microbe colonies) and reduce the need to have electrical gear inside the aquarium. By using 2 or more, we can run them from different airpumps increasing further the redundancy. Not taking time to "cycle" your filters is the biggest mistake people make, the second being incorrectly cleaning filters in tapwater and the third forgetting to use dechlorinator before topping up with tapwater. 3) Stable pH -> using coral sand as a substrate Coral sand, once cleaned, makes a nice bright substrate. This is good because it means we can use lower lighting and due to the reflection on the sand, achieve a result you would need far stronger lighting to achieve on a darker substrate. Axolotyl prefer lower light so thats a plus. It will also usually be nice and rounded, which is nice for soft bodied axos to crawl over and better when they inhale it while striking for food. Coral sand is made of calcium carbonate, this means that stomach acid will dissolve it! Organic waste is often acidic, but rather than dropping the aquariums pH, it will instead dissolve a bit of the coral sand. This will hold your aquarium at a stable pH of around 7.6, ideal for the filtration microbes we are cultivating in our sponge filters to compost the raw sewrage (ammonia and nitrite) into non toxic fertilizer (nitrate and phosphate). Our testing has shown our local tapwater to be consistantly at or close to 7.6 which is excellent as it allows us to do larger water changes without the complication of having to adjust the pH of the new water to prevent pH shocking our axos! So, good aeration, good filtration and stable pH. There are 3 other considerations, worth investigating when using the above strategy. Water changes to keep nitrate and phosphate diluted to prevent algae blooms. The easiest way is to test nitrates and get into a water change routine that keeps them diluted below 80ppm. While you need a nitrate test kit to be able to test nitrates, you only need to test and record nitrates for a few weeks to have a good idea how much the food is raising nitrates by, and thus how often you need to water change to keep them below 80ppm. Good nutrition, not just an eternity of bloodworms. While bloodworms are often readily accepted by axolotls they are not a very nutritionally complex food and so should be part of a varied diet. While they have a reputation for being tricky to feed, as long as water quality is good they will take a surprisingly large variety of food. Live earthworms are likely their favourite but not something that's easy to keep on hand. Frozen foods such as bloodworm, brineshrimp or even beefheart, are usually taken readily. The most difficult feeding happens when freshly hatched and for optimal survival rates requires living moving food such as baby brine shrimp or baby mosquito larvae. For adults though, you can feed a large variety of sinking high protein pellets. These are not only far more nutritionally complex than single ingredient foods like frozen bloodworms but can be loaded into auto feeders while you are on vacation. The more smelly the food the easier to introduce it, so foods marketed at catfish tend to do particularly well. Many breeders use smelly aquaculture pellets designed for use with salmon or trout. We recently tested ours with ocean nutrition colossus Q2 with great results. Medications Being basically frogs with tails, axolotyls are suuuuper delicate to medications. There are not many meds that wont outright murder them! One we have found to be effective and safe is Indian Almond Leaves. These seem to improve tapwater, and help prevent infections on injuries. They work by putting tannins in the water, which many are not a fan of, due to it meaning yellow water. Usually using them would risk rapidly lowering the pH but with a coral substrate buffering the water you can have tannins and a stable pH.
  7. Breeding tetra Tetra, like all big groups of fish, have easy species and tricky species when it comes to breeding and raising. Due to small fry size they are often disproportionately tricky to raise, compared to the ease with which they spawn thousands of eggs. With that in mind let us look at the example of the Serpae tetra, a species I have had great success with even as a novice aquarist. First here is a great link that should answer any detailed question. http://www.ctsa.org/files/publications/CTSA_1386316728568618675601.pdf Second here is a great tip from a great man,
  8. A common claim is that a good fish keeper, keeps water not fish. And you cannot argue that water quality is a huge part of the hobby. Partial water changes are our standard tool for keeping water quality good, and todays tip is a small one, the final check we do after a water change. Ensure after topping your aquarium back up, that you check that your filter outlets are rippling the water surface. Many of us push them down lower during the initial draining, or just due to evaporation, so its easy on top up to accidentally leave them down low where they are not rippling the water surface. In most tanks the surface agitation that oxygenates the water is produced mainly by the filter outlets. So the final step to a water change is to re-adjust the filtration nozzles or spray bars, or even wavemakers, to ensure you have optimal surface agitation. This is also important due to many dechlorinators lowering oxygen levels as they remove chlorine, often made worse by tapwater having a low oxygen content to start with. Get that surface ripplin and you degas the CO2 and get that oxygen loaded back up :)
  9. With the warmer water comes an increase in life, some of which can cause issues for your fish. The dreaded flex is likely the most feared, as if it reproduces out of control it can wipe a tank in a very short time. Known by many names as a result of its many symptoms, it can be a very confusing disease to diagnose and treat. I highly reccomend taking the time to read through this link https://fishlab.com/columnaris/ Its important to know when to turn the heater up or down while treating sick fish. Whitespot turn up Columnaris turn down. Your 2 most likely disease encounters, know thy enemy!
