callistra, the Yahoo! link does not say what filter that fish was sucked into.
The 2nd link is for the AquaClear 20, which is not the filter that is used in the Bow aquariums.
The 3rd link says nothing about what filter was used.
4th, is a regular 5 gallon aquarium from WalMart which carries a much more powerful filter than the Aqueon filters.
5th is a filter from a 10 gallon starter kit, not the filter we are talking about.
6 says nothing about what filter nor does it say exactly how he was stuck.
7 the OP said he "I know he probably got sucked into the intake", note the key word "probably". This also does not mention what filter was used.
8 says their Betta darted under a huge filter for a small aquarium and his finnage started to get sucked into the filter, which happens if a Betta gets too close to a filter, actually it happens to any fish who gets close to a filter. It doesn't mean the whole fish was SUCKED into the filter like you keep saying happens all the time. If it happened ALL the time then no one would use a filter with a Betta.
9 also says nothing about what filter was used.
I don't know if you are aware but we are not talking about any old filter we are talking about the Aqueon Bow filter that comes in the MiniBow, 2.5 BettaBow and 5 gallon Bow. The filter looks like this:
There is no way possible unless the Betta was a fry for it to actually be fully sucked up into the filter like you keep saying, it's impossible. However, a Betta can get his fins torn in the filter intake, which is why we suggested the sponge or cheesecloth. The intake is not nearly strong enough for a Betta to not be able to free himself from so there would never be any fear of a Betta drowning because of the intake or having serious bodily injuries. It's completely impossible, please understand what filter we are talking about and don't post unnecessary threads that don't pertain to what we are talking about.
