"Teacup" Ray ID?

  • We are currently upgrading MFK. thanks! -neo
What is risky about them?

I have read that they are generally very docile and will only go after other fish if they can fit in their mouth. I have heard that they sometimes don't get along with their own kind though. I will rehome one of them if that becomes the case though.

Are marble motoros and mini marble motoros the same thing? I have heard that the mini marbles only reach around 9-12", depending on male or female. My LFS has a Ray labeled as a marble but it doesn't say mini.
 
There is debate on mini marbles. I bought mine hoping they would be minis since minis apparently are from Columbia and have triple perimeter spotting which my two have. My male is also fully rolled at 11 inches. Only time will tell.
 
The tank is going to be focused around the fire eels, which might turn into one if the start not getting along.

I will start the tank with the eel(s) and 8-12 discus, depending on how I feel about how they fill out the tank. That will be it, except for a ray or two, if they will be ok. That is what I am hoping to get some opinions on here about. I would really like to add one, but only if it will be alright to do so.
