A friend of my wife's heard that we were getting into tropical fish and gave us her cycled 10G tank. All that was in it was 2 Albino Cory's. I went to Walmart tonight and got 3 Fruit Tetra's and 2 Dalmatian Molly's. I read all the info tags and bot said that these 2 fish are fully compatible. The tags also said these fish were good in small numbers with out being in schools. Now that I have them home, I looked up the fruit tetra's and, not only did I find out they were dyed, I also read that they are school fish (need at least 5) and that they will fin nip the Molly's. Am I going to have an issue with these choices?
