Melafix. Ok that is what my friend recommended I use. They are young fish. I have them in a 10 gallon tank right now. I had the tank set up for a month before I put them in there. I havent been changing the water very much, about once a week. I have been trying to get some good bacteria in there before I do it more often. The levels are in the safe zone all except for the Stress level is a little high. What can I do to make the water better for them? Again, I am new to this and I am doing everything I can to help them. What are the antibiotics called and where could i get them. Thanks for the help!
