I've had my Nic in my 125g for 18 months and it has grown form 3.5" to 5", this seems awfully slow to me. In the same period my ebjd went from 1.5" to 7", six months later I added 4 1.5" geo iporangensis and they are all 6-7". With good growth from everyone else and the Nic being very active with bright healthy colors I know I'm doing my part. Is this slow growth rate typical for Nics or is he a runt?
