Some of these fish have clear markings but this batch I am not sure. Hese fish I found in O'ahu waters.
1)The pair butterflyfish are probably the common forcepsfish but to me the snouts it too long making me lean towards the longnose.
The others I presume is the millitseed and the chocholate dip cromis.
2) some kind of millet maybe. didn't expect to see it is 4 ft of water.
3)the squirrelfish I think are Hawaiian squirrels - xatherythrum
