- Colony. Isopods are gregarious and are kept as a group – 10 to 20 animals to start; a single animal cannot breed. Only one species and one colour morph per tub: a faster-breeding species crowds out the slower one, and morphs of the same species interbreed back within two to three generations.
Notes
An easy-care beginner's Cubaris; the damp corner must never dry out completely; cuttlebone or calcium matters for moulting; watch the ventilation (mites and mould). The colour forms (Mandarin, Papaya) are the same species.
