I don't know about amazing but I was really starting to not like whatever that crap was growing (I assume hair algae) and did a bunch of research on what would eat it.I do have some sponges popping up. Its amazing to watch the tank go through its stages.
The Kole is probably going to get too big for that tank. It'll grow to about 7-9" and get about 4-6" from belly to dorsal. I think @ptreef saw this coming when he asked for it when you need to rehome it back in May.My tangs are getting too tall to go under the frag rack. I'm going to have to either lower the rack or raise it however I'm not too keen on either.
I'm leaning towards opening up the middle of the tank and put the acros on a pvc-scape type deal. I saw an interesting video from TSA - basically using PVC instead of tonga branches. I think it'll look like hell but then again - its a frag tank so....who really cares if everything is growing well, right?
