100 gallon fish list

joe0813 · Jul 31, 2026

Hey guys, I have a 100 gallon tank that has been running for about two years now and I kind of want more fish but worried it might be to much. Some fish came from my 180 before we broke it down to move some are new. I am upgrading to a 350-450 once we finish the basement which is our 5 year plan.

Here's what I currently have.
Yellow tang from 180
Purple tang from 180
Pair of clowns from 180 female is 13
Melanarus wrasse
Royal gramma
Flamehawk
Yellow assessor from 180
Purple firefish
Regular redfish
Rollands damsel

What I want to add
Mandarin I have pods dos them bi-monthly
Starry or lawnmower blenny
Pintail/flasher/fairy wrasse 1 male 2 female

I would say with both zebrasoma tangs and the melanurus wrasse, you are pretty much fully stocked. More bioload might work, but I think agression might become a bigger problem. I think you can still go for the mandarin, but would skip on the blenny (as they are not the smallest) and the wrasses until you can upgrade

The two tangs surprisingly don't fight at all. I got them both when they were about two inches and now they are huge. But maybe adding more fish might change it
