How many plecos can you have in a 90. I a going to get some tomorrow. The tank has drift wood and tons of algae. I am wanting a gold nugget or a royal. My LFS has blue phantoms currently, (new shipment tomorrow). I have to get 1 to get rid of the algae (I will leave with one more are just a treat). So in short how many plecos can I get for my 90 once they get to 6in or so I am willing to sell, also this tank is going to be a discus tank by the end of this year.
