   The Blue Spotted Stingray or Blue-spotted Ribbontail Ray are one ot the most unusual marine animals available. They have two plates in their mouth which are used for crushing the shells of crabs, prawns, and molluscs.

   This ray would take squid and shrimp from our hands so you could feel the plates in the mouth. For the first few feedings we impaled food on a long pole and placed it very near the mouth to entice the ray to eat. Once they get the idea they eat almost anything.

   The spots on the Blue Spotted Stingray or Blue-spotted Ribbontail Ray are usually blue or light brown. The tail is slightly longer than the body and has a spine, the stinger, about halfway down the tail.

NOTE: Be very careful when handling these animals as a sting can be extremely painful. If you do get stung immediately soak it in hot water and call a doctor!

Out in the wild

The Bluewspotted Ribbontail Ray, as it is also called, will grow a total of 28" including the tail! The body will grow to just under 12" and this ray will need a tank that is beyond most aquarists reach. A tank that is over 300 gallons is needed to help them feel comfortable, along with a sandy bottom and only a ledge to take refuge under. Use water that has no traces of copper or other contaminants that are typically found in tap water. Use reverse osmosis or deionized water. They are difficult to feed, and need live shrimp or marine worms to get them to start. This is for an advanced aquarist. The tail's spine can inflict a painful wound.

I hope someone will reply to this.

How big are all of your aquariums for these rays? It looks as though a few of you have experience keeping them, and I am trying to find SOLID information on size of tank requirements.

Please if you can respond to I would SO appreciate it!

    My 265 aquarium is seven feet long and arranged specifically to accommodate my Blue Spotted Sting Ray. I think this should be the minimum sized tank for this species as he requires open space and live rock to behave as if he is in his natural habitat. It is important to note he only eats live food (shrimp).

    The gallon size is not what you should worry about as opposed to the foot print size of the tank rays need a lot of room to roam I have a blue spoofed ray in my wife's frag table that is 90 gallons but the foot print of the table is four feet wide by five feet long so a very sizable foot print. Now as soon as my 300 gallon tank is done cycling he will be moved to that tank for his new home. Lots and lots of research is what needs to be done. Happy days

Hello, I am a professional aquarist at a large public aquarium. These rays usually get too big and need more space than a typical home aquarium can provide. They also tend to do well in the beginning of there stay in home aquariums but usually die an untimely death. They will breed in capitivity if they have enough space and we supply local wholesalers and other public aquariums with the T. lymma that breed here.

There are ways to take pressure off the animals that are popular in the aquarium trade. Only buy animals that are hardy and will have enough space in your aquarium. Just because a fish store is selling it doesnt mean it is a good choice for anyones aquarium. DO YOUR HOMEWORK and be a conscientious aquarium hobbyist.

i love my blue spot! its my second one, the first one i had was in my tank about 5 months and it died. im sure it was my fault though. i added some medicine to my tank to take care of a 20.00 yellow tang and ended up killing 4 of my fish! including the yellow tang. so i bought another blue spot stingray and have had it for a year now. he is doing great. what a funny fish, he eats right out of our hand. he never messes with any of the other fish. he is about 10 inches round now and about 16 or 17 inches total length. i have a 180 gallon tank so there is plenty of room for him to swim around and enjoy himself {or her} not really sure what it is. i havent been able to keep any other rays in my tank, they dont seem to live more then a few days. but at least this one is doing great. well good luck to anybody else that is gonna get one.

    I just got a blue spotted sting ray but he refused to eat. I have soaked the silver slider with garlic, he took it underneath him and a few minutes later, he push it away... Any suggestion on feeding him? Thanks

    Try squid tentacles from local fish store . cut them small enough for the ray to get usede to it.  I have found the tentacles irressitable to rays. good luck . odds are against keeping any rays for any length of time.
