Thats about the size of crocea that I have in my tank. (5") Its doing really well. I have heard that they are supposed to have MH
's but I've heard that they will do just fine under PC
's. Maybe not as well as it could under MH
's but its still doing really good IMO
. I've heard that you can't have a maxima without MH
's from multiple people but I like the croceas a lot better anyway!
Like Lando said though keep your clam up towards the top if you get a crocea. You shouldnt have any problems then. Good Luck!
