I'm starting another 30g tank, but this time i am going to give brackish water a shot. The water (with water conditioners) has been running for a week and i added marine salt directly to the tank today (monday). I know you should not add salt directly if you have fishes living in the tank, since i have none i thought this would not be a problem (correct me if i am wrong). I checked the Specific Gravity and it was at 1.007, is this OK for juveniles GSP's.

1. I am wondering how much time should i wait before introducing the first fish, since i added salt directly to the water.

2. I intend to put some Green Spotted Puffers (GSP) in it, but i read on an article that GSP are not ideal specimens to cycle a tank. Is this true? If it is, what type of fish do you recommend me? GSP will be the main attraction, any recommendation should be either compatible with or eatable by the GSP's.

3. I was also wondering on any possible tankmates as well as # of GSP for a 30g tank. Any suggestions? Please include ratios and if's


Any help will be appreciated

Really, cycling a tank w/fish is old school. Read the article on fishless cycling in our Library or instant cycle w/Bio-Spira.

There is a good article also on GSPs, read that too. 1 adult GSP/30g.

You might wanna drop it down to 1.005 and then slowly drip acclimate the puffer in a bucket over several hours until they match SG.

You should not add fish until you have cycled the tank. See here for the fishless cycling article. http://www.thepufferforum.com/articles/ ... hless.html

The articles on GSPs is here: http://www.thepufferforum.com/articles/ ... togsp.html

GSPs do not make very good tankmates, and will be happiest alone in the 30 gallon tank with lots of decorations to explore and water current to play in.

Please feel free to check out the rest of the library as well, and return with any questions you might have

Thanks for the replies
