  1. I wonder if the GPG's would be more interested in sexytime if there wasn't 10,000,000 goldfish in their bedroom?
  2. ..alas I'm down in Melbourne where Riffle shrimp appear 1-2 times a decade at the LFS and by that time they are in fresh water. In theory their range extends just across the NSW border into Vic near Mallacoota...but due to their rarity in Vic they are listed on the Fauna and Flora Guarantee as Endangered and its illegal to collect them or own them even when they are common as muck in NSW and QLD..... somewhere I have an email that says its ok if you buy from a shop or a mate sends one in the post I'm a fair way from the beach so when I did this in the past I mixed artificial seawater and greenwater from my duck pond. This worked for DAS and Caradina typus a couple of times but there were a gazillion failures (suspect food related). I had Riffles for a couple of years and they only spawned twice for me.... so I only had 2 attempts which failed to rear any. My attempts were documented on the AL forum - the thread is still up but the forum is mostly spambots now. Also look a the overseas guys breeding Amano shrimp which have a similar life cycle. Have a go @joshthom... and good luck.
  3. Larvae are planktonic and they are attracted to light. I shone a torch in at night and siphoned them into jars where I could manipulate the salinity. I tried raising them in varying concentrations of salt water with green water mixed in without success. I suspect the green water (algae cells) were not the right variety or not of the size the plankton could eat.... all the larvae died in a few days with empty guts. I have managed to raise Darwin Algae shrimp this way in the past as they also have planktonic larvae that need salt water.
  4. I don't think anyone has ever bred them in captivity. I have gotten close and have isolated their planktonic larvae but could not keep them alive. The larvae develop in estuaries in salt water and move back up into the rivers as adults.
  5. If those GPG decided one day to start eating goldfish they'd be in breeding condition in no time.... More power to your arm @Grover65k
  6. Agree! Its not rocket science.... How'd you go OP? Kick that LFS in the teeth yet?
  7. Refer your previous posts - you didnt cycle the tank and its possible that now the fish waste ammonia has reached toxic levels in the week since you added fish. Read this: https://www.thesprucepets.com/ammonia-poisoning-1378479 You need to: (1) change 50% of the water immediately to reduce the concentrations of ammonia/nitrite (use dechlorinator). Stiring in a couple of teaspoons of non-iodised salt can help reduce the toxic effects on the fish. (2) ASAP add bacteria either in the form of mature filter media from another tank or as a "bacteria in a bottle" treatment you buy from the shop. (3) ideally get a water test kit and test your levels of ammonia, nitrite and nitrate and compare to the graph in the link I gave you last time.http://www.theaquariumwiki.com/wiki/The_Nitrogen_Cycle ...alternatively, take the living fish back to the shop and keep one of the smaller dead fish rotting in the tank for the next month to cycle the tank - then in 4-6 weeks when your water test kit shows that you have zero ammonia and nitrite you can go back to the shop and buy fish for your cycled tank. Your fish store advice was terribly inadequate IMO.
  8. Then please read the link on the Nitrogen Cycle I posted. You have started a "Fish In Cycle Method" which works provided you don't overload the tank too early. Its a bit of a shortcut - which your get-out-of-jail-free card is written in the section titled "Seeding Material Cycle Method" - that last bullet point since you dont have another tank. Phone a friend or make friends with your local shop owner to get some mature media. Do consider that bigger filter
  9. Did you cycle the tank first? http://www.theaquariumwiki.com/wiki/The_Nitrogen_Cycle If not then don't add more fish now. I'd get the bigger filter and run both in parallel for a month or more first.
  10. I also like the Makemyled lights - many of the models have lenses that can be added to focus the lights to penetrate deeper tanks. On my planted tanks I use the 10000K XB2 tubes. I put 2 tubes over a 4x2x2 with 90 degree lenses but 3 tubes would work too. Since I got mine they have brought out a number of powerful panel lights that have varying levels of adjustment and look better on the top of a tank (tubes are good in a hood or under a rack in the fishroom - the XB panel lights are effectively the same as 2-5 XB2 tubes stacked side by side in a panel). Fred @ Makemyled is pretty good at answering questions too.
  11. You'll get repeat questions because you opened two posts with the same questions and poeple may not see both. It is easier for people to follow if you stick to the one topic here:
  12. Great dimensions on that tank. I love a wide shallow. Would like one like that for freshwater plants. is that a divider I can see half way down or just a reflection on the glass?
  13. I make my own from PVC pipe. 700 litre tank. Bigger is not always better - the trick IMO is to have some turbulence where the water goes into the reactor to help dissolve the CO2. ie strong filter pump and don't make the inlet too big in diameter so the water squirts in. e.g. for my big tank I first used a 40cm length of 90mm pipe with end caps to make the reactor body with 3/4 (20mm) inlet and outlets and the water moved too slowly so would not dissolve all the CO2. I chopped the top off the reactor and put in a 50mm->90mm reducer so the inlet of the reactor is narrower (ie the whole reactor is pear shaped) and I glued a small piece of 13mm pipe into the inlet hole to make a bit of a "jet". So now the water squirts into the narrow top of the reactor with a lot of turbulence, but the larger bottom section slows the water down and traps any bubbles. Works well. The DIY "cerges" using clear water filter chambers are also great because you can see what is going on - but again good flow/turbulence is the key.
  14. My QLD Rhads in Melbourne get rainwater. Thankfully I found some predatory fish to eat some of the fry because these Rhads are way too happy,
  15. I want babies. You have told them we're all waiting ?
