Other Parameters Tricky to acclimatize unless close attention is given to providing good water quality with plenty of oxygenation.
Jump to next section Husbandry Information
Feeding Does 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.
Furniture Plants are not necessary but are left unmolested if present. Prefers flat rock caves to all other forms of refuge.
Compatibility Some 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 Tankmates Best kept with other fish that like a good water current.
Breeding Unreported.
Breeding Reports There is no breeding report.
