Hey everyone, I've had a 40 gallon long tank set up for probably less than two months, right now it is only housing rosy red minnows, but soon I should finally
be able to set it up as a high current tank for hillstream loaches.
My question though is about the lighting for the tank.
I originally had two 24" lights across the top, but needed to borrow one of them for a 15 gallon tank I set up, so the 40g has been set up for awhile now with just one half of the tank lit, and I almost want to keep the tank this way.
The fish seem to enjoy going over to the shadowed area a little more than the lit section, and I'm not concerned about plant growth or anything, so I was just curious if theres any negative consequence to this(other than people thinking it doesn't look as good)
The fish seem happy, and the tank seems to still be healthy, but I figured I might as well still ask the experts!
