The Puffer Forum

First let me explain the situation in our house,
We have 6 tanks running in our house right now, sizes run from 5 - 75 gallons, 2 are saltwater display tanks, 50 and 75 gallon, 3 are 10 gallon and one 5 gallon. I decided to use one of the ten gallon QTs to start a brackish tank for a way too cute GSP. right now he is about 1.5", how long until he needs his tank upgraded?
Also I heard that they can be fully saltwater, when and how gradually should I up his salt? Or should I leave him in the 1.010-1.012 range?

First stop is reading the very thorough article on GSPs in the library.

weez1959, you said you have a porcupine? Your tanks don't seem big enough to keep a porcupine. Minimum tank size recommened on the site is 120g, although I wouldn't be comfortable having one in less than 200g!

Really depends on his current size...the best policy is to have a fish in the end tank...but that may not always be practical...

I think he said his porc was about 3.5", correct me if i'm wrong weez1959.

My bad...never read all the posts...still 3.5"...at the size and once QT is done, one of the other tanks will suffice for a time...but that is a whole new post.

Sorry for the side bar..off topic...this is me zipping it

, we do have a porc, he's my daughter's, an impulse buy but now that she can't live without him she'll have to upgrade once again! She just bought a 50 gallon about 3 weeks ago to accomodate the little fatty. last week he was 37 grams, 3.5", how big can he get by this summer?

Anyways, not the original post,:P
I was wondering about my GSP... I was considering housing him in my daughter's previous tank which was a 33 gallon (empty right now) but I don't like it's shape, it's 22"tall x 29" wide x 12" deep, I would prefer less tall more length so he'll be in the 10 gallon for a couple months while he's so little. I have a lot to consider with him, he may eventually end up in my 75 gallon but that's if I gradually up his salt to full marine, or he could have his own tank with maybe a BB goby (if I can find one).

by the way, Spoot, I'm a she, Weez is a nickname I got from my nieces and nephews, when they were young, they couldn't pronounce Louise

Sorry for sidetracking your post! Your GSP would be a lucky fish to be in a 75g. Our baby ceylons have grown about from about 1" to 1.5" in 2 months. Not sure if the growth rate will be the same for GSP.

To answer your Q, at 2", I'd start upgrading to at least a 20g, winding him up in a 30g, by 4".
