I'll warn you now, people are going to get on you about two things:
1.) Not just one, or two, but three species of clown fish.
2.) Why is the PT in a 55 gallon tank when you have a much more suitable 135?
Clownfish are damsels.
If you want to get technical about it I count 7 species of damsels, the skunk, saddleback, ocellaris, yellow damsel, humbug, domino, and blue devil.
Seeing how clowns can live up to (( and over )) 20 years, 3 months is nothing. And I have a very very strong feeling that WWIII will break out once a pair forms and starts spawning.
I just see a lot of bad things happening in this tank in the not too distant future.
