I have a 20 gal and i plan on breeding feeders for my O and JD. Im not looking to have feeders 24/7 but to have a treat once a month or something would be nice. Which would you choose between and what are your experienecs. Examples of thngs that worked for you or friends, etc.This is a single tank project. Thanks in advance. (ive been doing the convict thing for a while but theyre so fast. I also realised i had one that survived for a couple months with the parents and has been eating all the next generations -_- So i fed her o my O.. who caugh her like 2 hours later lol)
