I know peacock eels are nocturnal and stuff but are there and ways to make him come out of the gravel of caves more often?Sometimes I see him every other night and sometimes I don't see him for a couple weeks.He is on a 40g with 2 angels, 1 pearl gourami, 2 long-finned black skirt tetras, one id shark, a huge common pleco, a bunch of little smails, an apple snail, a wild caught HUGE snail, and some trumpet snails (I will get some nitrate snails soon).
