GSP 40 gallons for life?

[FruitFly]

Hi everyone. I am looking at setting up a GSP tank but I have a few questions. At what age should they be at full marine? And, with the proper appliances, is a 40 gallon tank enough space for a full grown GSP in full marine?

check out this article: http://www.thepufferforum.com/articles/ ... togsp.html

it'll answer all your questions and more.

A 40g will be fine for the life of a single GSP. They will attain ~6 inches, so 30g is considered the minimum and 40g is better.

The article describes approxamately at what length they should be for each level of SG. Basically, the key is to raise it gradually. There is no real set rule on when to have them in what salinity, simply that they have been known to do best when in brackish water up to marine conditions.

If you haven't bought the tank yet, remember that length and depth is more important than height.

I have had this tank for years with variouse inhabitants. It has been empty for a while now though so I was thinking about setting it up again.

Be sure it's totally cycled before adding the puffer. Either use the fishless method (excellent article in our Library) or Bio-Spira, at the same time as adding the puffer (best poured into your filter).

Thanks for the links guys. I was thinking about the fishless cycle rout. No worries. I wasn't just going to toss him in.
