Three small blue damsels, 2 clownfish, a marine goby, coral beauty, and a small helmethead cowfish (which i will have a new tank for. He is only a square inch right now)

A real basic rule of thumb is 1" fish per 5 gal in the new aquarium (15") and up to 1" per 3 gal in an established tank (25"). Using adult lengths, you have 6" of damsels, 6" of clowns, 1 to 3" goby (depends on kind), a 4" coral beauty and 1" of cowfish for a 20" total. That puts you towards the maximum for your tank, maybe 1 more.

BUT!!!

You have a cowfish in with Damsels. IDK if I would ever consider that as the cowfish can poison the entire tank if he gets stressed by the mean damsels (and even potentially the clowns).

Cowfish efficeinados please chime in.

The only thing worth mentioning is that the adult cowfish size is not one inch, it is one foot...

Send a message via MSN to mr_X
I wouldn't be using the inch per gallon rule in a salt tank. I would research each fish and figure out what they need specifically.

My cowfish wont be more than 8" but i will have a new tank by then. He is only 1" right now. They are all very happy fish actually. The tank is large enough they dont stress eachother at all. My cowfish is super happy. I hand feed him and give him plenty of attention. Maybe ill get rid of the damsels. I dont like them anyway.

as mr. x stated, there's pretty much no use in applying the inch rule to saltwater. as for clownfish in with damsels, they are actually related to damsels, therefore its not really an issue in mixing them.
The Clownfishes, Damsels of the subfamily Amphiprionae, Part 1

you really need to individualize and specialize your stock list. both the cowfish and the damsels could possibly cause problems.

I dont personally see that being an issue. Ive seen several setups that successfully housed a cow/box fish. I cant really say the same for damsels. At some point in their lives they will become lil terror machines.
