My tank is up and running well (I think). Six female bettas, lots of plants, 6 ghost shrimp (guaranteed 3 still living), and one golden apple snail.
33 gal, 75-78 degree range, filter. Going to get the water tested this afternoon for more specs.
I've noticed a filmy layer on top of the water, almost like oil, only it does not have the rainbow sheen of oil. I've heard of protein film, but not sure if this is it, or if it's something to worry about. I have a betta log, and this cloudy whitish substance has settled on the bottom. Doesn't seem to effect the girls, I just wash it with hot water and a toothbrush to remove the slimy substance.
The other question is about the filter. I've noticed lots of bubbles. At first I thought it was from the filter, but then it was around the betta log, and it looked just like a bubble nest. But after moving things around I'm not sure if it's from the filter or the girls. There are bubbles under the out pouring water, around the intake tube, and all three sides of the aquarium on that side.
