Who Gives A Fish Forums

Yep, lighting and nutrients are key. Also, how often are you doing water changes? If it's been more than a month, you might wanna cut it back to every two weeks. Old water can get sketchy even if the params look good.

Nope, sorry to say, but that lobster's gonna be a nightmare for the cichlids - it'll shred 'em to pieces, just like it would with pretty much any other fish in that tank.

Your tank is absolutely stunning, I love the setup. What's the tank size, by the way? I'm actually considering taking over my dad's spare tank, it's been sitting empty for ages.
