not this 55, with a yellow and a lavender tang and all the other stock. None of those tangs should be in their separately, let alone all 3 from the same Genus Zebrasoma. Tangs of the same body type don't get along with each other, these fish generally wouldn't get along in a tank 3 times that size. The only possible temporary saving grace is that you introduced them all together, but watch your water too, introducing too much too fast can cause ammonia spikes. If the Lavender Tang is a Purple Tang, that makes the situation even worse, they are very aggressive as far as tangs go. IMO
should have never sold you all those fish, including the Mandarin, it was very irresponsible and greedy to do. Unless you are feeding live pods
to the Mandarin he will die, even with a healthy population in your tank, he will quickly eat them all in a 55.
1 Tang might do Ok, 3 all of the same genus in a 55 will not.
The clam will need more light than 2T5's.
I would pick out which Tang you want to keep and return the other 2.
Hopefully this helps, good luck.
