Recently bought a group of 20-24 Tropheus. Great colors & eating like crazy.
What I've noticed is that they stay on the bottom when I turn the aquarium light on.
It takes them a looooong time before they start to move around (or until I feed them).
When I turn the light off, they start swimming normally. The light I have is a normal
Coralife T5 lighting. XP3 & AC110 for filtration. Water movement is good.
My question....is the light too bright? Maybe more foot traffic now then what they were used to?
I've tried moving some rocks around but still the same.
Any advice....greatly appreciated!
