I have the blind down most of the time, just had it up as I was cleaning today. They've been there for about 2 1/2 weeks and are doing ok, but I will definitely move it if I notice any algae.
I used to have pet hermit crabs... Their food smelled SOOO good, almost like bubble gum . They were pretty cool and were very low maintenance, I liked em, but for some reason they died No clue what happened...
