how clamped is it?
« on: November 22, 2010, 03:05:01 PM »

Near as I can tell there is: fins all clamped, bottom sitting with clamped fins, fins are all clamped, fins are sometimes clamped.

And clamped fins mean stress.

But mellow-orange with fins beautifully displayed while stationary and "very-very stressed if you don't do something soon I will go mad" with fins on lock down while stationary are two extremes. So I wonder. First, is the stress fin relationship linear? Second is it a legitimate diagnosis to say something like "the fins are clamped half way"??

I will illustrate my answer with two pictures:

Healthy goldfish, erect fins Smiley

Sick goldfish, clamped fins.

An average healthy goldfish should be swimming around in a balanced way with all fins erect and no difficulties in moving or maintaining buoyancy. Now, if a fish is sick, you'll see that it's putting the fins closer to it's body and keeps them that way, usually combined with an unwillingness to swim.
Healthy fish can sometimes put their dorsal fin down closer to the back while they're speeding forward, but you'll notice that they soon put them back up again like sails! Smiley

Clamped fins show that a fish is uncomfortable either because of the water or some kind of infection, in other words, they're stressed, and a fish usually doesn't have "half-way clamped fins" but if they're uncomfortable, you'll notice them being far less energetic! You can see that the fish on the second pic looks rather lethargic, while the first one is wiggling himself to madness.
They don't clamp the fins unless there's something wrong, simply, it doesn't matter how "severe" the problem is.
