Twitching - then a knock out

[markwill]

Well, having got some discus to the egg stage about 15 years ago (never got wrigglers) I thought I might remember the initial signs for an "interested" fish. But now I am not so sure...

I introduced a lovely Red Melon into my tank a couple of weeks ago. S/he (I'll go with "she" since it just seems to fit - we call her Sunny!) is doing fine and today - after a water change - noticed that she was "twitching" and pecking at a part of a piece of artifical driftwood. However, I didn't notice any obvious "target" for this behavior so I thought I'd just wait and see.

Anyway, about 10 mins later I heard this dull thud (dashing around the tank). I looked around and noticed that Sunny was flat on her side and I saw no movement at all (fins, gills, etc). I thought she was dead. Then about 20 seconds later her gills were moving and about a minute later she came upright and slowly started to move around. 5 mins later it was if nothing had happened. She has no marks whatsoever that I can see. And she's twitching again...

Anyone have any idea what's happening. She is eating and swimming around as if she is very healthy.

Thanks.

hard to say what the "teenagers" are up to ;)

Thanks Carol. Am I to take it that a discus apparently knocking himself out (to the extent that there is no movement whatsoever, not even at the gills) isn't particularly unusual?

It's not common, but I have seen them get startled and bounce off the walls or lid haard enough to know themselves out for oa second.
