First of all I would like to say Hello, I've been looking around these forums for a while (via google searches etc) and I've decided to join!
So first of all id like to say hello!
Now to the interesting stuff! Ive seen Motoro Stingrays for the first time in my local aquarium shop and I instantly fell in love, Originally I was told by the guy in the shop that they don't really need that bigger of a tank, he recommended a 6ft x 2ft x 2ft when I asked what sort of size tank they will need, I later went home and started my months of research and found out yes, a 6x2x2 thank probably would do... For about 6-12 months! (must have forgotten to mention that part the nib witted douche bag) But anyways, basically im here to find out for sure what a size tank I should be looking at, Also if you do post an answer in gallons or litre or whatever please not that im from the uk, Im not to sure if our gallon is different to yours ): Don't worry I am not planning on jumping into this in a rush, I am the first to admit I am new to this whole fish scene, But take my word for it I am learning more each and everyday thanks to forums etc
Looking forward to hearing from you all, Thanks for reading guys!
So first of all id like to say hello! 
(may have to come up with a new name as il defo be looking for a male now) I have looked up on how to tell the difference between males and females, But until now I wasn't really aware of how much of a size difference there was between males and females, Before talking to you guys I was just going to get whatever one was available and that I liked (.: So you guys have probably saves me 109 pounds and a lot of disappointment! Would you guys recommend any kinda of sump? ive heard you can make your own using another fish tank? Would you recommend that option or would you recommend a branded sump? Again huge thanks for all the advise guys
