My problem with scaping is that i have a huge amount of FLAT rock which is a complete PITA. I pretty much have to break the rock down, and glue small pieces. And I'm pretty insane about the way I want it to look, so I keep rearranging stuff which is terrible, I know.
Hopefully once these are glued in, I'll have a decent and FINAL scape, which I hopefully will never touch. You've alreday got a pretty much perfect scape for a tank that shape, and with those fish. Since they like to pick on rocks, they'll look really neat between the caverns.
I'm having a huge problem with diatoms, courtesy my ro/di being rubbish. Have changed that. Added a small sea cucumber against my better judgement and he's really slow. Still waiting.....
