New Rbp Tank

Here is a picture of my new RBP tank. It is 65G and currently houses a pair of quarter sized babies along with a couple of Bristle Nosed Plecos and a small school of Rummy Nosed Tetras. I assume that those will probably need to be removed at some point as the piranha grow, but as of right now they want nothing to do with the rest of the fish. The lighting will be toned down a bit also...I turned it up for the picture. I have the LEDS totally covered on the right side to allow some darker areas. It is run with a 30 gallon sump. Would you make any changes? I purposely left out all plants....this tank was a high tech planted tank before this....I REALLY want out of the plant business for ease of maintenance.
