Ray confusion

[Ranzan]

Just thought ide clear some confusion in the blue spotted ray area.. There are 2 species or rays that share the name blue spotted ray. The one that does not do well in captivity is the blue spotted ribbin tail ray http://z8.invisionfree.com/Sharks_and_Rays/index.php?showtopic=193 the other species in the blue spotted ray which aparently after reading this does pretty good in captivity http://z8.invisionfree.com/Sharks_and_Rays/index.php?showtopic=222.. i dont know how many people knew this but i hope this helps any new ray owners and keeps them from buying the ribbin tail :D

Yeah - the Blue-spotted Ribbontail (Taeniura lymma) is poorly suited for captivity & very hard to keep alive more than a few months.

The Blue Spotted/Masked Stingray (Dasyatis kuhlii) is much better suited for captivity because it's a much hardier species.

if the blue spotted didnt get so big i would try toget one for my new tank but 14.5 inch disk diameter is a bit big and i would like 2 rays in my new tank.... Kinda off topic but does anyone know the number of gallons per cubic foot

[krj-1168]

With rays or sharks - it not so much about gallons per cubic foot - as it is about tank footprint.

For most rays for home aquaria - you want the tank length to be at least 4-5 times the Total Length of the ray, and tank width to be at least 1.5 times the total length of the ray.

So for a 16" long ray - like the Cortez - the minimum tank size would be tank with the footprint of standard 180 gallon.
