Those are great fish to control Aipts, but the minute all Aipts are gone, your Zoo's and Paly's are next ;) These are one of the best aiptasia assassins next to Berghia nudis.
Learned the hard way myself. Colonies gone just like that.
Best sand cleaner IMO, tiger tail cucumber
Have them for years. same one gave me 2 babies. one passed away a while ago, but never nuked the tank.
But if you want a fish sand cleaner, Dragon Sleeper gobies.
I would contact planet orange and see what methods they offer considering its not a cat or dog and you cannot move the tank. Bombing/tenting the house would probably be detrimental to your tank (not an expert)
