i rescued a baby moor from an uneducated but well-meaning friend a week ago, and immediately began treating for swim bladder problems since the fish spent most of her time either upside down or corkscrewing wildly thru the water. [treated with peas and interpet swim bladder meds - formaldehyde]. she's looking LOADS better

but still spends a lot of the time sucking in air at the top and blowing bubbles. it's like she had to do that a lot to try and regulate her swimming when she was in the old tiny tank she was in, and hasn't quite figured out that it's not totally necessary any more! she's in a big 15gal tub with a filter and airstone, water params are good, but filter IS being cycled...any ideas, or is she just a bit slow
