Robb in Austin Posted December 11, 2011 Share Posted December 11, 2011 For the last few weeks my main GBTA has been acting weird. It may correlate to my Clarki's finally laying eggs, which they do right next to/under the nem, but can't quite remember. At night it puffs up as normal, but not near like before, and when the lights come on the tentacles shrivel away to nothing. And today, the mouth is all open with the innards appearing to be exposed. (I haven't tested in a few weeks and will post a pic later along with new test numbers.) My RBTA and baby GBTA are behaving normally. No recent changes in anything. Any thoughts?

mFrame Posted December 11, 2011 Share Posted December 11, 2011 My various GBTA and RBTAs have acted similarly at different times, where they will almost 100% deflate at night rather than just retreat. As you mentioned, I did notice it a lot more on nems that had egg-laying clowns. It may be that the clowns are just battering it with the extra attention and aggressiveness they're prone to when they are defending eggs. How large is the GBTA? Have any tank conditions changed recently? If you try to target feed very small pieces of food is the nem responsive at all? Quote Link to comment Share on other sites More sharing options...
Robb in Austin Posted December 11, 2011 Author Share Posted December 11, 2011 When it was inflated this AM it was probably 8" across. Previously, within the last 6 weeks, it would get up to about 14" across. About the only thing that has changed I can think of is possibly cooler tank temps due to this cold spell(no heater) but I haven't checked so not sure. I haven't tried feeding it, I rarely do anyways, since it's been doing this. It's just weird how it inflates at night and shrinks during the day. Here's a pic: Update with test numbers(I'll update with more later): SG: 1.024 Temp: 77F pH: 7.8 Alk: 6.55- the last time I checked, early Nov, it was 10. I suspect I run low alk more often then not.

Timfish Posted December 12, 2011 Share Posted December 12, 2011 If you figure it out I'm anxious to know Quote Link to comment Share on other sites More sharing options...
Robb in Austin Posted December 12, 2011 Author Share Posted December 12, 2011 I dosed some Alk supplement after the last reading but have not retested. Here it is now: Quote Link to comment Share on other sites More sharing options...
JamesL Posted December 12, 2011 Share Posted December 12, 2011 What about lighting? Might your lights be around the time to replace? I can always tell when is it time for my MH bulbs to be replaced. The zoa's/SPS growth slows dramatically, and LPS start to be a lot happier Quote Link to comment Share on other sites More sharing options...
Robb in Austin Posted December 12, 2011 Author Share Posted December 12, 2011 Yeah, the lights are ready for replacement. Quote Link to comment Share on other sites More sharing options...
(Bio)³ Posted December 13, 2011 Share Posted December 13, 2011 FYI my nem does this cause I feed it alot, it is what they look like when expelling all their waste since they have one orifice and one sac that works as intestine and stomach.

Robb in Austin Posted December 13, 2011 Author Share Posted December 13, 2011 I never feed mine, and he has never looked like this when expelling poo. Thanks for your input though. Quote Link to comment Share on other sites More sharing options...
