Today while i was at my LFS i was looking at there main display tank with 5 big rays in 2 of which are gravid. enjoy!
I think that its silicone on the nderside of the tank.cookiemonster;1311187; said:Awesome rays! What's with the circles on the bottom of the tank?
They are very impressivepotamotrygon;1311231; said:nice rays but i don't like the tank
They actually have 3 babies in aswell.mjuniorc;1311233; said:man i wish rays were around my area.... d*%@ i would love to have one...
Big bump on there back.fishdance;1312636; said:The circles are silicon glue blobs since they have used double sheets of glass (cheaper than a single thick pane) to make a stronger bottom.
How do you know when rays are gravid? Just from change in body shape or do they change colour/behaviour?
