Darius,are you trying to get yourself banned or what,you've pixxed off a lot of people in the bichir section with your holier than thow attitude and now.your doing it in here.
I also think that rays should have substrate but I don't go round with your attitude telling people they are wrong.
If you don't like what you see o n this forums don't come on,as all I've seen you do is diss people off!!
You ignore such things? You look over it just to piss nobody off? Why didn´t you told him to add substrate for the ray? Sorry but i will not stay silent when i see such things.
For the OP: Please add enough sand to the tank, so the ray can burry itself completly into the substrate.
