Big plecos are the best. Glad he is getting an upgrade. Bet he will love it. I do not have a common anymore, but my current plecos love courgette and sweetcorn, but will mot touch brocolli for some reason.
Lol the 900 will be sometime from now but he will be the first one in their.
He will be getting a much bigger tank soon, he still eats the same, he isn't bloated, just leaves less waste than he use to.
I thought common plecs don't tolerate their own type?
How do you sex them?
I was talking to a guy in my local MA about this and apparantly they are extreamly hard to sex before full maturity. They have two in their 5000l display tank and they get on fine so in the 900g you should be fine with two.
