I picked this up the other day for our pleco tank, it was sold as a common but the markings look a little off now it's home and settled in I was wondering if any one could give me a number, I was thinkg 21 or 23 in the LFS but now I'm not sure.
Anyway I'll let the experts decide:

Sorry for the poor shot that tank is a nightmare to photograph as it reflects the other tanks
Thanks in advance
