Smallest Adult-Sized Stingray?

  • We are currently upgrading MFK. thanks! -neo
Rays have different attitudes but over all they are pretty placid. Two of my rays I could handfeed, pet, even pick them up (not out of the water of course)! My current ray, is a whole other story, as he is rather onry. While acclimating him, he damaged his stinger cause every time I walked by he would flip his tail up and wack the side of the cooler! Ive hand fed him and touched him since but Im no where near as comfortable with him as my previous rays.
 
I keep a colony of wc moba frontosa, 3 small bristlenose plecos, 1 freshwater flounder (about 7"), and 2 freshwater african eels (orange spotted & leopard) in a 180g tank. My water pH is slightly about 8 and my water temp is between 77-79.

I have a sand bottom (CaribSea aragonite select) and have lots of holey rock. My flounder is not bothered by all the rock and gets around it pretty easily. The plecos don't mess with him either, nor do the mobas.

Do you think my tank set-up and water parameters are acceptable for keeping a ray? I do weekly 50% water changes. My water quality is really good.

What do you stingray gurus think?
 
Now Ive heard of rays being kept in hard alkaline water but your parameters are pretty much opposite of the soft acidic water they are naturally from and would concern me a bit. But if Collin thinks its aight listen to him hes da man! LoL
 
Plecos are not good tank mates for rays, they will latch onto your ray and suck the slime coat off the ray until it dies. And what about a Yepisi, they only get to about 18".
 
female motoro about 14 inches. He said if he wasnt being sooo stupid around her that nite it would not have happend but she stung him in the finger removing a small amt of flesh because she hit him so close to the edge of that finger. It hurt like a m$#@f@##@kr!! Its been 4wks ago and still hasnd completely healed yet. His finger (thumb) looks bad since I saw him last week but hes on antibiotics. He said it still hurts like a sharp nagging pain. Lesson learned...dont be drunk stupid with your hand in the tank because you never know how the ray is going to react irregardless of how long you have had them!! Pretty sure he's learned his lesson now.
