Would it be possible?

Yeah I think your only option is to make it. I know there are some on amazon, but not sure of the size

Probably i could buy i kritter keeper and drill some holes for the suction cups, just in case i dont find anything at the stores.

Something like this probably with a couple modifications?

Have you thought about a net or mesh breeding box? I've seen some 10-12 inches wide and pretty deep, great water flow, not quite as see through as plastic, though, which might be a good thing.

Just be really careful with anything that is suctioned capped to the wall of your sorority. I have some 4L mesh breeders' nets that I use to house fish in tanks. However, I have noticed that the suction caps on these are very poor quality (these weren't the cheap option either) and usually stop actually sticking to the glass after a while underwater.

I came home once to find one expensive HM male dead when the suction caps holding the net in place failed and he fell into my sorority. I'm sure they had a great old time tearing his fins off.

After a couple of near misses I stopped using them as I was too afraid another fish would be injured or killed.

I have the Satellite breeders' box you linked to, and it is pretty small for a permanent home for a full-grown betta. Plus I found it to be very noisy with the water pumping in and out. Otherwise I didn't really have all that many complaints about it.

Thanks for your advice. I probably try to find something tthat hangs on the back.
