Same-species behaviour

The source recommends more than six fish and a footprint larger than 180×45 cm. Too few fish can cause nervousness; aquatic plants are likely to be eaten.

Diet and feeding

Combine plant foods, prepared feed and suitably sized live or frozen foods; do not feed an exclusively meaty diet.
