I picked up a little one (~3"), and placed him/her in my 40 gallon tank with a couple hundred endler's. One of the CCA members collected it in Peru back in January, and brought it back in his suitcase. I won it in the club auction. How quickly should I expect it to outgrow a 12" (front-to-back) tank with all the live food it can eat available?
I tried that with a small clown knife once. In about 7-8 weeks the bugger outgrew my 55. Hopefully the Carapo will be a more manageable size, I have several 75's now.
