Thanks Rob! I still can't believe the Tanzies are keeping up with the Gatf in growth. Have to agree, their tails are definitely something else, but it seems only the dominant fish's tail shows true color. Might be an odd coincidence, but seems there's only one vibrant tail at a time, and if that one is traded off or killed by a ray, another one steps up and fills the role. Possible? OR crazy overactive imagination?
Unfortunately most of the fish in the tank have tattered dorsal fins. Think I'm going to get an 8' tank set up for the Tigers. Going to try adding some more Dithers and maybe the little Vs once it's going. Need the Tiger's 6'er for the Armatus.
