Well.... I have a 60 litre BiOrb life - which to look at is a fantastic tank and has served me well as a general fish tank for over a year
BUT.... since i decided to make it a tank for my female bettas... 2 so far have dissapeared... only to find that they have been wriggling underneath the filter which is about a 5mm gap.... and dying
I have saved a few since...that ive seen swimming around in the filter, but with the new arrivals due, I need a solution.


Any ideas? apart from ditching the BiOrb?
I will just buy a new tank if thats the only solution..

My juvie fry used to do that too in the biube lol

might be worth putting a bit of tights around filter bottom and put an inch of gravel in.

I've kept the top of the filter box bare so its easy to get in and out for replacement
