in my 30 gal tank there are 2 jd's....i know they need to be in a bigger tank, but $ is tight right now. my male is about 4-5 inches, and the female smaller than that. ive had them for about 3 months, and have regularly fed them cichlid pellets and/or frozen bloodworms, my question is this...is it possible to feed them feederfish? if so what should i use, something relatively inexpensive, and is it okay to use the flash when i take pics of my fishtanks? thanks for any help.
