I have had a small GBTA for nearly 2 months now and it has very long skinny tentacles. I am not concerned that they don't bubble just that the tentacles are so skinny. It does not look completely comfortable. My params are all normal.
pH 8.2
SG 1.025
Nitrates 5
temp 79-80

Hosted by a 2" clown - does not seem overly agressive.
Whe it was orinally put in it was on a small shell. I have since persuaded it to move to a larger rock thinking that perhaps the shell was not big enough. It moved to the top of the rock but I have this rock isolated from the rest of my rockwork to prevent it from moving everywhere or getting near the PH's. I have tried higher flow, lower flow but it jusy never seems to make a difference. It eats well atleast 2-3 times a week.
So could it just need a higher place in my tank for more lighting?? (Came from MH lit tank) If so should I allow it to find it's spot by "roaming" the rockwork? Just seems like I may be looking for trouble with the PH's and stinging of other corals.
Any ideas? (This is one of it's better days, sometimes even skinnier and longer)
