So i was cleaning out my larger aquarium and I had clipped the tube to siphon out the water into the tank and i was using the other end to wash out my filter, and I happed to glance up in time to see one of my female bettas decide to investigate the clear tube in the aquarium. needless to say she is a slender fish and the tubing was not very thick. she got about 6 inches into the tubing and got stuck, i did not have enough time to react. I spent about 2 minutes trying to blow on the other end of the hose to try to dislodge her and was successful. Other than having a very red face for a few minutes she seems fine like nothing had happened. I think I was more traumatized than she was. Any one else have a similar story? and should I invest in a thicker tube to clean out my aquarium?
