Hello!

My ADF tank has an awful under gravel filter built in that would extremely tricky to remove and replace. I was told to go ahead and use it anyway and the frogs have been getting on fine for almost two years now. If they are ok with that, I assume they will be ok with most filters.

To feed I use a turkey baster to squirt the food onto a little plate in the tank. It keeps things a little tidier than other methods I've tried. Also, if I know one frog didn't get much food the last time, I can use the baster to direct food down to a particular frog (if the others don't see me doing this first, hehe). I have one frog that will often get there first and eat the lot, then if you put a bit more in for the others, it will come back and eat that too bless..
