I’ve got 2 that I’ve had for 5 years now. They’re about 6.5 inches and they’re in full saltwater now. Kept em with mono Argentina forever and now that’s it’s saltwater I’ve added some damsels to clean up the food messes. They get big fast if you do the water changes and give them some tank space to roam. Once they’re full grown, frozen shrimp (shell on) from the grocery store seems to be their favorite food. They also don’t bug my hermits for some reason, so more cleanup crew you can have. They did try my Xenia corals, but didn’t like them

I’ve had mine for quite sometime now, and I dripped him over to full marine (1.025) and he’s been doing great in my reef tank.

Zenzo another great video, thank you from NYC

[darthanubis]

Put mine straight from fresh to full marine and they did great. My local fish store also does this and they havent had a problem

I’ve owned GSP before and I love love love their unique personalty. Cute fish with a green glowing head and interacts with humans. What more can you ask for in a fish

I’ve had one for the last 4 years in brackish water and he’s literally a puppy ina fish bowl. Such a cute personality and he can tell us apart! His eye sight is so amazing. Mine eats nails and blood worms. Mine is still small though. Does it take them a long time to get full size?

I love my green spotted puffer I transitioned it to saltwater when it was a baby into my reef tank had it for 4 years. He gets along with my hippo tang and clown fish. Thankfully mine does eat flakes and anything even algae. He will go after my hermits or snails in my tank.

Amazing top-notch footage. This is such a great video for helping people decide if a gsp is right for them. Or just watching and enjoying

I was given one of these a few years back when I only had a freshwater tank. I thought I was just being given a bucket of assorted catfish and cichlids. I was given a small green spotted puffer in the mix. I knew what it was but I didn't know what to do as I only had one tank. I initially put him on pure fresh thinking I could get a 30 gal in a few days for him. He didn't make it past the first 2 days in pure fresh for me. But he was in pure fresh for a while before then and by the time I got the 30 gal in... it was too late. Regardless, they are a fish I intend to try again at some point. I also have a saltwater tank for them to move into now so...

I have several bumble bee gobys, knight goby, black molly, 2 figure 8s that are in there temporarilly and then 4 GSPs. I was super lucky because they are not aggresive at all but they have been in the tank with those fish for 3ish years. A friend of mine got a GSP that just kills everything.

[christopheranthony]

Can you do a vid on figure of 8 puffers

[billgarner]

Enjoyable introduction to an interesting fish. Thanks, Zenzo!

[CrazyAquariumGuy]

Hope this spreads, so stores stop selling them as freshwater! All have done it where I have been.

I used to have 2 gsp’s somehow they got along fine their entire lives they were such awesome fish truly like pets with personalities etc

Please help!! I purchased a green spotted puffer as a freshwater fish and was told it was a pea puffer. They said I should keep it as a freshwater fish and she has been doing good but not thriving. She had an abrasion on her belly when she first came home with me that I was able to clear up and it went away but she also developes black spots all over her belly starting from the sides where her color is then starting to go down into the white of her belly. I want her to be taken care of but I never signed up for a brackish water fish and have no idea how to keep up with that set up. I'm willing to get her the set up she needs I just want to make sure I'm doing it right. Please tell me what I should do to help the transition and give her the best life possible. I kept looking up how to help a pea puffer and the images looked totally different from her and I finally found out that she's a green spotted puffer. They told me she wouldn't get bigger than an inch and a half...

A high quality informative video 😊, thanks for the info 💯

[SlayByJay]

I also read since their so smart, it’s wise to change their tank frequent and break their line of sight otherwise they get bored very easily

[wiseman]

Love you guys. Great video like always.

[iPhoneSEman]

Thank you. You just answered every I mean every question I had on this fish. Your the best

My LFS sold me one this past week and they kept their stock in their saltwater system. I buy my saltwater there as well so parameters are similar and it’s doing fine. Specific gravity is 1.025 normally. He has been thriving for a week so far eating frozen mysis shrimp right off the tongs.
