Who could be the culprit?

Hi, I got home from school today and noticed the bubbler had been 'unsucked' off the bottom of the tank and was floating around, attached by the airline. The suckers do degrade and lose their suck but...
My fish are:
- 5 zebra loaches
- 3 banded garras
- 2 pepered cories
- 4 glass cats
- 1 bristlenose
The only fish I could think of was my bristlenose, but all four suckers unstuck?

Highly unlikely a fish was involved - the bubbler is so bouyant as it's full of air & as you say the suckers do degrade after a while - also if the surface it's stuck to is not totally clean it will hamper the suction

Apart from the BN, Garra could also be the cause.

However, just as Richard wrote, I don't think of any cause swimming. Your air comes through an inflexible tube, and therefore, I think that after a while a few suckers came loose - resulting in more work for the remaing, in fact, most likely too much

I myself use large airstones, large enough they never float, regardless how much air goes through them. Perhaps you can find them as well - they measure 4 cm or so across (that is, as you know, 1,5 inch)

I'll just stick it to the back wall and see what happens now.
