Common name: Maroon clown, spinecheek anemonefish, yellowstripe maroon. Scientific name: Premnas biaculeatus Origin: Indo pacific. Max size: About 6 inches Reef safe: Yes. Actually, a really good addition. Can/will form symbiotic relationships with anemones, un-suspecting corals and, even powerheads. There are charts and suggested/recommended anemones to pair up with the maroon clown. However, I have seen maroons (clowns in general) host anemones that come from parts of the ocean that don't even have clownfish. Mine for example is hosting a bubble coral shown in the pic above. I would suggest a "bubble anemone" for a good host to the maroon clown. An anemone is not required to keep a happy/healthy maroon clown. Here's a chart for reference. Clownfish Anemone Compatibility Chart Attitude: Known to be the nastiest of the clowns. Not compatible with other clowns. Mine measures up to about 1-3/4" and I've had it since it was muuuuuccchhh smaller. I have not had the pleasure to experience this "bad boy" attitude as of yet. It really only seems to squabble with my leopord wrasse when it comes close to it's bubble coral. Quickly submissing when the leopord backs him up. It has also learned that when my grn. mand. dragonette makes a pass to completely ignore it now. I would assume that the fishes territoriality would drastically change when paired up and during mating/breeding. Diet: Meaty goods. Mine doesn't shy away from nori and other seaweed particles floating through the water column at feeding time. Breeding in captivity: Known as one of the easiest clownfish to breed in captivity. Even without a host anemone present. Since, I'm not a breeder and most info will be referenced, I will leave it at that. If you decide to get into breeding, info is easily found on the web. Personal opinions: I find this to be one of the most attactive of the clownfish species. I particularly like the manner in which it swims. Looks like a shark cruising through the water. The deep maroons and subtle black markings along with bright white or gold bands give this fish a distinct look. An easy fish to keep that readily accepts feeding/food offered in the home aquarium. Weird/cool facts: They can change sex. They grab food and take it back to their host. It's un-known whether they do this to feed the host. Or, to stash away a cache. There urine is beneficial to some un-suspecting host corals. It's known as a spinecheek because they have some pretty nasty looking spikes at their gill plates. It's actually a damselfish. Thanks for reading. Please add a pic of your maroon clown if you have one. Share additional experiences to.
