The smallesttank that should be used to house a ray is one with a base of 48x18!!
Height is not an issue as rays do not need a high tank, but it should be a minimum of 18" high!!
Rays are very easy to keep!! Their only requirement is PERFECT water conditions...0 ammonia, 0 nitrite and 0 nitrate at all times!!
I received my rays on Monday and already did a 30%water change on their tanks last night!!
You must also remove all uneaten food within a half hour of it being uneaten. this ensures the food does not have a chance to in anyway pollute the water.
As for "stinging" rays do not go out of their way to use their barbs!! Rays are actually quite peaceful by nature.
Most ray stings happen because their owner is careless and does not pay attention while their hands are in the tank!!
Rays are quite quick....when my rays arrived and I was preparing to place them in their tank....I thought I would be able to pick them up by hand as this is how most ray keepers do it.
Well I got the first ray up and out of the box and it was a good thing I was watching it's tail because it swung it's tail around and almost got me. I was able to place it back in the box before this happened.
Out came the nets!!!!!!
As long as one is always watchful and does not let themselves gey distracted, one should not worry about getting stung.
These are my first rays, and although I have been keeping fish for a VERY long time, I read up on them for several months prior to even thinking about bringing them in.
They are truly beautiful creatures and well worth the effort to own.
I, have of course picked out one to keep for myself!! I will be starting a ray tank of my own as I am already addicted to them!!
