Alternative Ray Diets - Collective Brainstorm?

Freezing kills parasitic cestodes such as tapeworm.
In theory it would be safe. Then you should also take into account what the fish have been exposed to (chemically).

Is it a safe body of water? Can you be sure there is not a source of pollution?
 
I've been researching a bit on rays, and i was thinking that Malaysian Trumpet snails would be a great food for most molluscivorous rays. They breed like mad, hide in the substrate like ray food would in the wild, and they're probably very good nutritionally. I hope to have a bunch in my tank for rays in the future.

Also, i get this finely crushed rock substrate out of the local river. The water at the stretch i get this stuff from has helgamites and stonerollers, so the quality is good. I've seen various small critters crawling around in the substrate, but i've always dried the substrate out before putting it in the tank, thus killing all the little aquatic insects. I was considering leaving it wet and just introducing it to the tank right away for my Lethrinops, which are sand sifters. The aquatic insects would probably reproduce in the tank, and i'd have a very natural food source. Would this work for rays? Leaving the substrate wet, and letting the critters reproduce in the tank? It seems like a good, free, constant supply of ray food, if only for smaller rays.

Any thoughts?

my rays eat the malaysian trumpet snails over the course of the day. they dont love them but theyll eat them. as for the river sand... i would boil it. along with the good stuff WILL come bad stuff. you can get argulus, anchor worms, tapeworms, etc. if you like th elook of the substrate and the price it right :naughty: then take a big ol dlobster pot or turkey deep frying pot and boil it for a while to kill anything that could get into your system. make sure to stir so that all the sand comes in contact with the boil! good luck
