They spend time ranging from rocks, to wood, to plants, and always have full bellies. One seemed to want to suck on the larger ancistrus for a while, but I think they settled their differences.", (13) scrup, (14) Alisana, (15) mane1138, (16) This Old Spouse, (17) Arlington, (18) Jeffww, (19) rcjkirk (k: 7), who also notes: "Somewhat delicate when first introduced into the tank. Expect some losses of the weaker fish. After that, they seem to stabilize and become quite hardy.
