Sponge Filters for Betta - how to set up
I have 2 bettas both in their own 2.5 gallon tank (aqueon 2.5 with minibow filter.
I've noticed that one betta avoids any current from the filter and my other betta gets blown around in his tank- zoom across the tank he goes. I can't imagine this being fun.. over and over.
I'm looking into sponge filters but i'm completely lost as to what i need to do, what i need to get with it?
can i just get a sponge and put it over the spout to slow the flow of water?
do i need more hose, a bubble, air pump?
