Weather Loaches acting weird (okay--weirder than usual)

[skitty14]

I've got 2 Weather Loaches, had them about 6 months, they're about 3 and 4 1/2 inches long, respectively. I've gotten used to them digging up plants, flipping over the "cave" and the general destruction. I still love the little buggers though. Anyway, they have taken to wedging themselves between the heater and the glass in a pile. The tank is about 78 degrees F. I know Loaches like it a little cold, that's why I'm at a loss for why they do this. The big guy is even sticking his face in the corner of the tank above the water line......
I'm on day 2 of Ick treatment, but they have been doing this for more than a week. Water is changed regulary, they're fed well and they would not have the Ick if the husband hadn't brought home some "pity fish" a few weeks back.
Thanks!

how big is their tank? Either it is their normal activities or they are frustrated and bored because they don't have enough space.

20 gallons. I'm going to start cycling my 10 gallon tank for their own place. As soon as I get rid of the Ick in the big tank, and the 10 is established again, I'll move them.
Thanks.

has your treatment got malachite green in as loaches react very badly to it

make sure the tank is VERY WELL COVERED!! as we have about a 1/2 inch between the filter and hood of our community tank, and our weather loach jumped out! just a bit of advice from our experience a few days ago. but i do not know the anwser to your question srry.

I'm afraid 20g is too small. These fish grow BIG a bit under a foot, I would say 100 gallons would be the minimum size where they could act and grow normally.

when u say weather loach do you mean "misgurnus anguillicaudatus" cause there are many other loaches with the same common name that don't get as big

10 gallons is way too smaall. get a 40 for them at least.

weather loaches act wierder than normal when its about to rain, or there is a front of low pressure. before a storm they are most active, they sence or can feel barometric pressure. hence the name "weather" loach
