My regal was caught doing a bit of nipping on a SPS luckily it wasn't and Acro, mili, or anything I truly like... so he wins between that coral or him.
I have added a decent amount of new acros and milis to the system. All the original acros have fully encrusted and have new growth tips.
I have been dabbling in the KZ product line a little. No way to truly prove it did anything, but I have never had fresh cuts heal, encrust, and have new growth tips within a month on a young system.
Using FlatwormStop, Coral Booster, Phols Extra, Sponge Power, Aminos
Could totally be a scenario where you want to see something and you convince yourself you see it.
