and by that I of course mean fish. Okay, I am slowly building up my 20g community tank. First I had 3 guppies which are doing great. I was going to add two dwarf gouramies next. But when I went to the LFS, the guy said I should do neon tetras instead (which I was planning on having as well). So I bring 7 home, acclimate them over a couple of hours, and release them. Immediately one dies. Then every time I look in there it seems there's another dead one. I have had 3 left since last night, hopefully they all make it. I tested the water last night and everything was at zero. I am thinking that maybe I stressed them too much. I have heard tht they are very sensitive to water changes, and that some people acclimate them over like 24 hours with a drip method. Are there other reasons they might have died so quickly? Is there anything I can do to increase the survival of the other 3? Should I get some more or wait?
