50g lowboy stocking frag tank

[Jake_the_reefer]

Hey guys, I'm looking to stock this tank, it's going to be 2 50g lowboy frag tanks that are plumed into a single 40g sump. I need utility fish and fish that act as a nitrate source for corals/macro algae

So far I'll be doing probably
Lawnmower blenny
Yellow coris wrasse (with a small Tupperware of sand for it to sleep)
Should I do chromis 2-3 of em
Any other ideas?

I use mine not only as a frag tank, but a grow out acclimation tank. So I keep some LR along the back wall and sand. I try to find expensive fish as juveniles (cheaper) and grow them out there. I keep 2-3 small chromis as dither fish, which means other skidish fish see them out and feel safe to come out also. The tank is very easy to maintain because of the height, but as far as utility fish there are always small wrasses and try to keep a small tang or bristle tooth which I move when they get larger.

I liked mollies for utility purposes when I had my frag tank
