none haha..
I run the stock hood that came with the 10gal and put in some of those screw in flourescents... one of my flourescents burned out so its been only running with one and I turn it on once in a blue moon since the hood is not hooked up to a timer...
They open up really big at night since they are mostly nocturnal imo and stay shriveled up most of the other time.. I feed them silver sides rarely and give some to the crab and hermit....apparently they can live in any type of water too haha.. I used to do water changes on it once a week then slacked off because I wanted to get rid of the whole setup.. Its running stock hood, a Topfin30 regular filter and a koralia one.. I just changed the water last night since 2 months ago and everything is living ok... I am even getting coraline on the intake tube for the filter which I find amazing since I have not changed the water, had the lights on or dosed anything.. hah
