Frogspawn - sweeper tentacles? throwing up it's innards? (pic included)

[gmate]

I've had three different colonies of Frogspawn in this tank for 3 months and have never seen a colony do this. It's a skinny thread(s) that come out of the mouth and float around. I thought it was it's guts which is what I've seen my mushrooms spit up when they get upset. I've never seen a frogspawn 'sweeper / feeder' tentacle so I don't know if this is it. Usually I spot feed these corals and whatnot. They've grown since I got them. This is one colony with 4 heads (was originally two, one is done splitting and the one that's spitting this up is almost done splitting).

Parameters:
Salinity 1.025
Temp 80
Ammonia/Nitrite 0
Nitrate .2-.3
PO4 0
(I don't test ca/mg/alk I just do large water changes 30-50% just about weekly)

After this tentacle thing was out for a few minutes it retracted it back in. The coral was kinda upset for a little and was not extending as much as it was previously. Any help is appreciated folks, I've only been in the hobby a few months.

Thanks,
Glenn

That looks like it had to take care of business. I was researching Frogspawns/Hammers since i have one as well and people talking about their "sweeper tentacles". I have have yet to see mine come out...but they look healthy and that is what is important!

I have heard people say that the coral does that when "pooping" lol

Looks like brown jelly might need a dip??

They don't really have sweepers, but having that toadstool next to it is a problem. THis coral needs fairly strong light, and will temporarily lengthen a standard tentacle to reach a neighbor. Give it about 6 inches clearance from all other corals downcurrent of it, put it near the inflow to get it water as little touched by softies as possible. Running carbon now and again is a good idea.
They also have a high calcium requirement (supplementation) once they get going. I raise these types, and its cousin hammer coral, and my params seem to be highly successful with this type.

The brown stuff is zooxanthellae (sugar-supplying bacteria and colorizing agents) being jettisoned via the mouth: it's been put into strong light too fast. Start it on the bottom and work it up a little every few days.
