These guys are really funny. They love sand, and made a cave under sand and DW and river stones - so they like caves and hideouts. Mine were bought from someone changing over their tank so they are adults (6). Love snails as Delapool mentioned as well as meaty foods. I feed mine lots of frozen defrosted foods, and they like the Hikari Sinking Omnivore wafers a lot too (orange trim package) and Seaweed Extreme. They are kinda, long little fish pigs.
New to FW fish? First tank in a long time or EVER??? Need some info on keeping fish?
