Runt

[Shikkapow]

I have a runt puffer (i think) its a GSP and I have had it almost a year and it is still about 1"
I feed it mostly bloodworms, but I do have a 45 gallon fresh tank that I grow snails in and feed to him every once in a while, I feed them ghost shrimp about once a week.
I maintain usually 1.004-1.008 SG but he isnt growing at all...
I bought a crawfish about 6 months ago and was worried who would be the dominant animal in the tank because thay were about the same size, now the crawfish picks on the puff, and is about 4 times the size of the puff..

do I have a runt or are gsp's just really slow growers?

First of all, are you sure it's a GSP, or could it be a dwarf? See: http://chunkypuff.net/projectpuffer/t_nigroviridus.htm

It sounds like you're doing all the right stuff for it.

Sounds like you don't have a GSP bud, but an indian dwarf puffer. My GSP that I got about 8 months ago was 1.5 inches when I got him and he's about 3 inches now, and that was just living in a 10g for most of that time.
