Hi there. About six months ago a friend of my husband's was moving and was going to flush his 5 fish because he couldn't be bothered moving them. I was horrified and although I know NOTHING about caring for fish I took the fish and the 10 gallon tank. I did some research, enough to get my tank cycled and bought a test kit. Unfortunately I emptied the tank out completely, scrubbed it down and bought a new filter and new gravel. I found out later that was a bad move . I have lost two of the fish to ich after treating them with something recommended by Petco (can't remember the name right now). A friend recommended this site to me and through doing a search I did find some alternate methods of treating ich which I will bookmark for any future outbreaks. I want to get more fish but I'm not sure how many more would be "humane" to put in a 10 gallon tank. Right now I have two tetras, one is about 2", one is probably a little over 1" and I have an algae eater, not a plecto, the smaller one, don't know it's name? But that guy is about 3". What do you think?
