Deffinately a RTCxTSN. Get ready for a huge monster. I got one last month and it was
2" smaller than my TSN. Now its double the size of the TSN and it ate one of his other tankmates his size!
Yup I agree 100% thats its a RTC x TSN as mines looked just like that a few months ago...and look at it now....i had it about 2" in January and about 8-9" now this very month! its almost passing my RTC size which is 9-10"
