Jump to next section Husbandry Information
FeedingInitially algae, add a shoal to an ''algaefied'' tank and then supplement diet with sinking tablets and the usual cucumbers / lettuce or courgette (zucchini).
FurnitureLarge leafed plants and vertical flat rock surfaces (especially slate). Not essential, but likes bogwood and a large rounded substrate. Live plants seem essential to the long term survival of this fish.
CompatibilityPeaceful.
Suggested TankmatesKeep in groups (preferably at least six) with any small to mid-sized community fish.
