Nudibranch question

[Trumpetytrump]

Are all of these bad for corals?
I have a Lettuce Nudibranch. Will this damage my zoos?
What about other softies?
Thx

No not all are bad, only a few really are notorious for wreaking havoc in our tanks. Most nudibranchs are very selective feeders and cannot be properly cared for in a captive tank. Lettuce nudis are fine and won't harm your corals. They eat algae only. Only thing to worry about is having them get sucked into a powerhead
