I wouldnt keep a single maroon in a 20 gal either, and find it especially bad that you knew better to try and cycle the tank with a fish and you did it anyways when you had an ammonia reading.
Of course he is going to try and sell you something, its a store, that is what they do. Very few LFS actually care or have real knowledge of the hobby.
Chichi has 2 maroons in a 10, and she has been in the hobby for 12 years. I'm not claiming to know everything because although I have been doing this for a few years now, there is still SO much to learn., hence why I am here. Should I put the biocube skimmer on the 20g tank too? Wasn't sure if i should just get rid of the biowheel and keep the skimmer or run both?
