Just because I see other sites saying peppermint shrimp are reef safe- no not really, they go after the skin on Sps, eat hammers, will try to eat snails that are flipped over, that’s all worth it if they eat the AP nems first. The people saying ohh it’s the wrong kind , nah,, I see conflicting sources on what’s the ”safe” ones ways too much, so in the end they are not reef safe, if anyone wants pics of the Sps they have demolished I have some . If you have AP nems nudis are the only truly reef safe option but if swamped in huge nems , these guys are the way to go, then sump, overflow or return them. I will say they find new sources of food when needed so if you never forget to fed then it might be a safer chance. Lost a $300 gold hammer gone I had for 4 years bro, my purple stylo one hammered on for weeks with me thinking , let me check my alk, my cal, my phos, my N, my lights , let me raise my N , my P, no that’s not working let’s lower them to nothing , ouch other corals are suffering now,one night I see one of the shrimp carving off skin on my sytlo. Ohh ok it’s the dang shrimp . When they decide something is food , kiss it good bye, now this was a 8 inch wide colony I have now had to cut up and it looks like trash. the shrimp would carve holes on the corals skin then Algae grew on those spots making it the ugliest coral of all time. For those who want to get rid of the peppermint shrimp they have , cut a 2 liter bottle in half and stick them back together bait the trap and they will be in there in a few tries, they are so fun to watch , I loved mine for the job they did killing my nem problem but from 9 I had to remove all but two, these two are on watch now.
