I have a 35 gallon aquarium with the following fish:

4 figure-eight puffers
2 bumblebee gobies

My figure-eight puffers don't seem to be growing at all. My question is why arn't they growing?
The salinity:1.006
Foods given:All kinds of frozen foods, live snails, freeze dried foods, live guppies(only for a treat)
Water changes: every 3-4 weeks.
 
How long have the fish been in there and what size are they now? It is a bit of a high bio load for a tank that size. Water changes could also be a bit more frequent, like 50% weekly.
 
I'm sorry to hear you lost a puff. I think really stepping up those water changes is the most important thing you can do for them. 50% weekly until all water parameters (nitrite and ammonia at 0 and nitrates 25 or less) are in line, and then you will still need to do weekly, but you may be able to do less than 50% depending on how the nitrate is reading.

I am no expert, new to these forums tonight, but my figure 8's havent grown much either. They appear to be pretty slow growers. I have had them about 2 years now, got em at a hair over 1" long and now they are probably 1.5". If you think 3 fig8's and 2 gobies are to much bioload in a 35 then I guess I am probably way over... I have 3 figure8's, 2 knight gobies, an anablep, a mono, and a scat, in a 40gallon tank. I havent lost a fish in the 40g tank yet. I had a lot of plants in there at one point to help out with the bioload, bult I neglected the tank over last summer and the salinity went way up mostly from water evaporation and most the plants died. Need to re-acclimate some plants!

Puffers are among the more easily stunted families of fish we keep. If you don't allow sufficient gallonage and swimming space, your fish do "...appear to be pretty slow growers." The technical term is "stunted".
