these guys flouted to the to of my refugium & only there & not on the main tank. so far everything seems normal, but there are easily about 100 of these guys. i have skimmed them out with a cup. closes hing i can compare them to, is a nudibranch. the large ones are roughly the size of a grain of rice. thx ahead for the help.

Ya they look like a type of nudi. Have you introduced anything new without dipping? Any zoas? I think zoanthid eating nudis are more brown though

yeah. i bought my self a huge rock of zoas, just cuz i spotted mj's on it, about a month ago & did not dip. got to exited. i did google the nudi you're talking about & looks very similar. hoping its not those guys, cuz i do have a few montis. but my melanerus & mystery wrasse are good at hunting anything. they are constantly, swimming around rock & coral, picking stuff out. thx for the reply jesuses :)

Eesh I would say 99% of the time you find nudibranchs similar to those in your tank they are coral eaters. Check the underside of your montis for eggs.

Only others that really look similar that we have in our hobby are Berghia Nudibranchs and those only eat aiptasia. And unless you bought those specifically then that's not what you have.

They take on the color of what they are eating, so they can be brown, green, red, etc. Usually just the tips change color though, but your right the body normally are white/tan/brownish color.

The zoas eating nudies I had took on the color of the zoas they were consuming bc when they ate they they absorbed their color. That is wat I read online anyway and wat happend in my tank. Good luck tho

I would blast your rock crevices and underside with a turkey baster so if there are any leftovers, they will float and your wrasses can pick at them better.
