Okay so to start. I had a 20 gallon tank that had 1 beta 2 cory cats and 1 turquoise rainbow fish. The tank sat that way from January ish to about a couple weeks ago. I then added 2 dwarf rainbows 2 boesemani rainbows and 2 more female betas. Everything seemed fine then I eventually noticed that...

So I've had my fish tank for about 6 months now, and my molly (who died about 3 weeks ago) had a lot of babies. There was one survivor and it's been fine til now. I noticed that it spent most of it's time just laying on the rock, barely moving. It breathes rapidly, and I feel like she's lost...

G'day.   I need a bit of help! I do apologise - this is not a tropical fish, it is a giant goldfish, I have taken it on board to try to get it back to better health.   So. This goldfsh came out of my brothers 1000L Aquaponics setup. it is around 30cm long. It was in with about 20 other goldfish...
