In spite of the fact that this thread is approaching its 1/2 year anniversary, I suddenly feel an urge to post on it again.
I'm sorry everyone.
Anyway I was poking around the forums here and I saw someone mention a wholesale site called "www.qualitymarine.com" and I came across this critter
http://www.qualitymarine.com/Products/Fish/Wild/Rays/Diplobatis-ommata/Electric-Bullseye
The "Bullseye Electric Ray" which, according to Wikipedia, only grows to 25cm. I'm anything but an expert, but 25cm is absolutely tiny for a marine (or freshwater) batoid. As I have since learned, even small SW rays require much bigger tanks than FW rays of similar proportions, but I still feel as though this could fit happily into a manageable 250-300 gallon tank. That same wholesale site has the Lesser Electric Ray that I asked about before, some weird thing (
Narcine Brunneus) for which there's absolutely no scientific information for that I could find, and a Torpedo ray (which seems extremely dangerous to me).
I have done a little bit of reading in the past few months and found out that electric rays (well, the Lesser Electric Ray anyway) has an extremely tough time adapting to captivity and often refuses to eat anything except live marine worms (and other things of the like). I'm going to assume this applies to the Bullseye ray too. Since I do not live anywhere near any type of saltwater shore would there be any way I could get a hold of a live culture of marine worms? I'd prefer raising them myself, or finding a reliable source for them.
Once again, all this is for (distant) future reference. I have nowhere near the funds or experience to keep any type of cartilaginous fish at this time. But never the less, I will be extremely great full for any advice you guys can give.
