I saw a little 1.5 inch flowerhorn at the lfs today, i have never seen flowerhorn around here so i decided i would get it, but the lady said she wont sell it because its missing half its tail. She said they would get some in on wednesday so im going to go back and pick some up, they are only $8 so i imagine they aren't that good of quality. I have a empty 20 gallon im going to put them in. Would 2 or 3 be ok in there for awile?
