would this make a good frag tank?

would this make a good frag tank?

No one has bought this yet so if it doesn't sell at the Quad Cities (fresh water) fish SWAP this Sunday I may turn to a frag tank.
I was thinking cutting the internal sump area in 1/2 making the tank only 20 to 25 gallons.
Hanging a dual ho t5 36" fixture (with two daylight bulbs) that would hang over it in the space created above the water but below the black area you see across the top at the front.
using the pump that is in there and a power head and small heater
a couple gallon water change a week I would be good right?
remember only thinking out load

 

it is a odd shaped 55
