Wife has never liked my choices in fish, so yesterday I took her to Petco, Petsmart and the Locally owned fish store. I wish I had done this long ago. She now understands why I spend more at the LFS than the chains. Cleaner tanks, happier fish, no overstocking the tanks and people that know what they are talking about. (This couple has run the store for 25 years) Now. She definitely wants Angels. The tank is a 75 Gallon Bow Front. It currently has 6 Serpae Tetra, 4 of the Glowlite tetras(not mine, came with the tank) 2 oto's and 3 guppies. I think it's pretty understocked at the moment. The Angels she likes are currently about nickel size(body) but planning for full growth how many are safe? I was thinking of sticking to two and adding some of her other favorites (Rummynose tetras) after a few weeks. Otherwise would 4 angels be too much at full growth? Thanks.
