Thanks guys for the great comments,i was going to get two endlis the same size but the mrs said there really nice you should get them,so i did,there was about 30+ in the lfs all nearly as good but i think i got the biggest and best!
And as for the bigger endli in pic 3,hes been stuck at 7" for about a year and was not really eating much but since i put a few more little ones in hes started to eat alot more so hopefully he will grow too.
Also ive moved them into the small NTT tank just incase,until they put some size on,which shouldnt take long.
