I have been trying all kinds of food. Live black worms, frozen blood worms, frozen brine shrimp, cut up night crawlers, cut up cooked market shrimp, pellets. I have krill, but I have yet to try because they float.
Water temp is right at 80F, I add twice the usual amount of salt. I have had them for a week now, and have done 2 50% WC. I am going to pick up an extra filter just in case this weekend.
Water parameters perfect and water is crystal clear.
