Well, the title kinda explains it... Ive had some BTA's for about a week and a half now.. they are doing fine, but their tenticles have kind of like dark spot where they keep bending due to high water flow... Is that alright or should I reduce the water flow/move the PH's around? or do they like high water flow?
