Will my tank be stocked too much?

[Chris_Noles]

So I have an IM 25 Lagoon and have a mocha clown, royal gramma and a six line wrasse. The other fish I would like to add is a coral croucher will this be too much for my tank? Also do these crouchers actually mess up SPS branching corals?

When breading they lay eggs around the base of some sps corals. This causes some STN but once the babies are gone the coral recovers.

They are cite little fish so post a poc when and if you get one!
