I have a 40g setup with 3 breidohri and 2 geophagus brasiliensis all fish 2-3.5 in, and I cant seem to get them to eat pellets Ive been trying the 1mm nls pellets which are more than small enough for them to eat. They attempt to eat but just spit it back out and then they eventually give up. How can I get these guys on pellets? p.s. Ive been feeding them bloodworms, and flakes.
