The couple would kill a pleco haha, but that lp190 pleco is nice i would like one but cant, I did a 75% water change scrubbed the rocks and glass and siphoned a bunch a poop from the bottom. My light is just a normal t-8 florescent that i do leave on all day and night because my jag for some reason freaks out when i turn off the light i think its because of a fight he got into with a 12 inch long 8 inch tall big ass buttikoferi that he lost one of his eyes to. very sad but hes back into shape after alot of recovery and got him a mate so he can settle down from being a street fighter to being a faasha.
