Sexual Differences: Males have, as in this genera, bushy tentacles to the mouth area and the females have them very small. Aquarium Care: As with most of this genus it will do well in an aquarium where it will wipe out any algae. Diet: Feed vegetable foods such as lettuce, cucumber and courgette (zucchini). Will eat most aquarium fare. Reproduction: The female lays her eggs in caves or crevices... that the male has chosen and cleaned.... as a cluster. The male usually then guards the eggs after ejecting the female. The fry then cling to the sides of the cave and when they use up their yolk sac, which is around the four to seven day period, they will be ready to feed on infusuria, vegetable matter, brine shrimp naupli or micro worms. In a community tank a few will survive if enough hiding places are afforded to them. Etymology: The specific name triradiatus: depicts the three soft rays in the anal fin peculiar to this species.
