agreed, also my blue spot would eat anything that would fit into it's mouth, mostly salt water black mollies due to their prolificness, later upgrading to gut loaded fiddler crabs. Also try researching removing the spine barb from the tail.... I did ours with a pair of needle-nose pliers and a quick dab of superglue, but that was many years ago. It was a bit twitchy and restless until the installation of a grounding probe to eliminate stray voltage. It ultimately outgrew the 120g sand bottom tank and was given to the local zoo, in San Antonio, TX for a better living environment. Amazing animals with a wonderful disposition (he/she) would beg for crabs near the surface if I was in the living room moving around, ultimately had to retrofit a better lid to prevent water splashes.
