Also, that tank you plan to get is not big enough for 3-5 rays. Its really not big enough for any ray in my opinion
2m X .5M X 1M = 78in x 19.6 X 39 (LxWxH) and that equals 250 gallons.
That tank is not wide enough for rays.
Nor is the gallons big enough for that many rays. Rays put off alot of bio.
Also, please do not cut or pull the stinger. It can be harmful and adds stress.
It would be like you pulling your finger nail out...
