Hey Mfk I am kinda new to keeping fish. I have had my 20 gallon up for about 6 months now with very little problems, my tank currently holds 6 neons tetras, 6 black phantom tetras, 6 kuhil loaches, and one female kribnesis. But i am about to get a monster tank (well its a monster compared to what i have now) and that is a 55 gallon and i already have some thoughts for some monster fish. but overall it is great to be hear
