pH6.2 - 7.0
Temperature24.0-27.0°C or 75.2-80.6°F (Show species within this range)
Other ParametersTricky to acclimatize unless close attention is given to providing good water quality with plenty of oxygenation.
Jump to next section Husbandry Information
FeedingDoes well on commercial "algae" wafers but requires a meaty element to its diet (probably met by insect larvae in the wild). Newly imported specimens need such meaty food immediately to acclimatize properly.
FurniturePlants are not necessary but are left unmolested if present. Prefers flat rock caves to all other forms of refuge.
CompatibilitySome what territorial. Defends chosen cave structure from all other plecos; ignores larger fish. Should have adequate space. Can be kept in a community tank if this is taken into account.
Suggested TankmatesBest kept with other fish that like a good water current.

Much prefers slate or stone hiding places to wood. Never saw it touch plants or wood at all. Loves fresh veg and meaty foods and does not seem to graze, is much more particular about what it likes. Never noticed it eating algae off any surfaces.", (14) smitty, who also notes: "Originally kept in 150gal tank. Moved to 180gal tank on 9/14/2010.
