HI everyone, I am going to Indiana for 5 days and as wondering if I should get those vacation feeding blocks, or just feed them before and hope they live? I was at my cousins for 4 days and when I came back one of my platys had fin rot. It acts fine, but it's fins have tears in them. I don't know if the other platy did this or what. At first the one with fin rot(or whatever it is) was dominate, but now the other platy is bossing the other around. So now the platy with torn fins is in a 1/2 gallon bowl with a little pot floating in the 20 gallon. My mom thinks the fish will be okay, but I'm not sure. I've heard pretty bad things about those feeding blocks, so that's probably out. An automatic feeder is too expensive for me and I would have to buy at least 3 for my 20 gal, 5 gal, 1.5 gal and 1/2 gal(I have feeder guppies in the two smallest tanks). Thanks for any help or suggestions!!
