I have two ten gallon tanks, both inhabited by a male Betta.
I bought two Aqueon deluxe hoods for both tanks, one in the store and ordered the other online. After I installed the one I bought in the store, this question keeps popping into my mind, "Should I leave the door open or closed?"
I have a Whisper 10i filter for the tanks, and the currents they were producing were a little to strong for the fish, so I rubber banded some aquarium sponges under the outflow of the filters, and now oxygen doesn't circulate through the water, but thats alright since Bettas can get oxygen from the surface - until I put the hood on.
There are cut outs in the back of the hoods for appliances & their cords to be placed, so does enough oxygen get through those to where I can keep the little door shut? I'm afraid if I leave the door open my fish will jump out...
Also, I plan to get some platy tank mates for one of the tanks, should I remove the sponge under the filter so they can have oxygen aerated through the water or should I just install an air stone?
Thanks a bunch!
