I am coming to this forum looking for some advice after a bit of a disaster last night. Before I get into the details here is what I can remember of my tank details:
http://www.seapets.co.uk/product-details/stkcode/950008/category/955.html (http://www.seapets.co.uk/product-details/stkcode/950008/category/955.html)
Airpump (cant remember model but I think it is rated for 60 litres)
Tank kept at about 26C
I started the tank for about a week before putting fish in (following the advice of my gf as she got me the tank as a present and had had fish before).
First fish we put in were (gf suggestion as she said these were hardy fish):
2 Zebra Danios
2 Black Mollys
10 Neon Tetras
After a month we lost the bigger of the 2 Mollys. It was about a few days later that we got some more fish:
2 Clown Loach
1 Catfish (not sure type, he likes to stick to surfaces and clean them)
4 more Zebra Daiios
2 White and 1 black Molly
5 more Neon Tetras.
After about a week we lost 1 white and 1 black Molly and 1 of the neons. The white Molly we think had an infection (he was sitting in the gravel not doing much and getting bullied by 1 of the white Mollys. He would swim up to the surface to get away and then do summersaults down towards the bottom of the aquarium) and the black we are assuming was the same thing. The gf isolotated the fish in a jar floating in the tank to give them a rest from one of the bulling Mollys and I dropped in some food but neither of them ate it. We used a chemical to treat it and none of the other fish died so we think we suppressed it.
Fast forward about another week to last night. I decided to do a water change as my NO2 levels were about 0.3 mg/L (I think that’s what the test said), Not sure if I did the NO3 test correctly. So the gf gave me a hand siphoning about 20-25% of the water out, I gave the filter sponge a clean in the water taken out. Replaced the filter and the gf put in some more treatment for the infection and topped up the water in the tank. I gave the fish a treat (to say sorry for disturbing them) of some freeze dried blood worms and a small square of freeze dried tubeflex worms and brine shrimp (1 cube of each) and left them for the night.
This morning disaster struck. The tank water was cloudy and the neons, danios and 1 of the Mollys were gasping at the surface. I turn the airpump off at night so I turned it back on and checked the filter and the temp (both ok). Looking around the tank I found 4 Neons, 2 Loach and the remaining white Molly had died. I think the catfish was still alive but he was hiding under the rock but I could see him breathing.
After about 15-20 min of the airpump being on the fish were not gasping at the top of the tank but had dropped down a bit but there breathing was still rapid.
Anyone have any ideas of what I could have done wrong or what has gone wrong?
