Hi, I am new to fish keeping and I have inherited/rescued a large green severum, it is about 6 inches long, I am unsure if it is a male or female. I keep Sev in a 30 gallon tank with a red tail shark and a couple of algae eaters. I am intending to upgrade to a bigger tank to accommodate this lovely green severum as it is quite a character. I have plants in the tank which Sev likes but occasionally he/she completely wrecks them ..picks up the pots, pulls the plants out and it looks like a bomb has hit the tank. Should I not keep plants with the sev and just put rocks in? I am worried that all the dead plant matter that is floating around will decrease my water quality and I find it hard to keep cleaning up after a rampage. What do others suggest that know this fish please.
