I traded in the angry Krib I had quarantined and got a nice GBR. It has long fins and is colored wonderfully. It is probably 6 months old because it is getting close to 2 inches. It seems to do fine with everything else I have in there, but I will give it a couple days before I can really tell how aggressive it is. I've always read that GBRs are peaceful so hopefully I have good luck with this guy. My water has been clearing up, so has the Ick on my Black Molly that is in quarantine, I will put him back in the main tank today. My CAE had a bout with dropsy and he has gotten better for the most part, still some red spots on his side from growing so quickly, my electric blue ram also has some redness on one of his sides but I think its a bruise from when I put my bucket in the water to do a WC. Just thought I would do a quick post to get some feedback about GBRs in a tank like mine.
