Well, it's been a while but, unfortunately, the tank has taken a turn for the worse. The twig cat got stuck in the short grass and died and the tank is down to its last few red phantoms (and one glowlight). I'll be transferring those guys to another tank and will refurbish this one. I just got some new driftwood and I don't think I'll keep such dense 'vegetation' - I'm still not confident enough to go real with my plants.
