Hi everyone, Ok so i have read a few times about bettas not liking strong currents or water flow. How do you tell they don't like it? Are there any signs to look for? I have quite a few betters, the filter types i have are 2 different kinds. One is a 2 stage filter, with 200L an hour flow rate and a current of 15 moving average. I can adjust the flow rate on this filter. This filter is in the main tank. The other filter is an Elite Mini submersible. Its 220L an hour, no idea of the flow rate but its fast, and adjustable too. This filter is ran in the back of the tank to push the water through to the air pump which then pumps water into the tank at 1.6L a minute. My bettas seem good with these pumps, in fact the bettas with the first pump like to swim in the currents of it sometimes. Id like to know about this because if its just that they dont like it im ok with that, but if its something to do with their health, well i would certainly like to know about that.
