Inhabits flat areas of shallow clear waters with low

Care: Not a well knowm species but good aquarium
husbandry with regular water changes and good oxygen
content should suffice. Diet: Readily

cucumber, courgette (zucchini), tablet foods, flake
foods, granular foods, frozen bloodworm, to name but
a few. Try also to provide rocks covered with algae
or other methods like this for this species as they
will feed on this, and also the very small microscopic
animals that are found amongst the algae.
