My GSP is acting wierd. help please

  • We are currently upgrading MFK. thanks! -neo
GSPs are not generally fish-eaters. They eat crustaceans. They bite chunks of flesh off other fish because they are aggressive & mean.
 
Just an idea - would you be able to set up a tank specially for it? Or a couple of them? You could keep one in a 30g tank because they get to about 6".

Maybe you could put in a mature filter or some of the media from your existing tanks into an internal power filter and slowly go brackish or full marine. If you have a hydrometer and raise the sg from fw by 0.002 units per week the filter bacteria should survive. High end brackish is very roughly 1.018, full marine 1.022 - 1.026 in sg.

I've two Celon puffers and the owner of the LFS told me himself they were fresh water fish. He's pretty experienced in most other areas of fishkeeping. I've seen the change in them as I've added marine salt. The care of Celon puffs and GSP's is identical apart from mine get slightly bigger.

Mine were in FW in the shop and got ich as soon as I got them home which I treated with high temp (30C) and aquarium salt at 1tsp per 5 gallons. And a shed load of aeration/water movement. I would have used copper being unaware that copper would probably have killed them because they are scale less fish. I did a 50% change each day for a month and kept them in FW until it went. It did.

I'm now slowly raising the salinity by 0.002 s.g. units each week until I get to 1.018 at least. That slow so I don't kill off the filter bacteria.

One of them also had IP's, being wild caught but I managed to treat that by injecting shrimp with Praziquantel and feeding it to them.

Slight battle, but they're doing fine now :-)

I feed mine on live crabs, crushed crab legs, snails, small clams and earthworms so they get enough variety. Next is to get some freeze dried krill and soak that in vitamin solution before feeding.

The crabs don't last more than a few seconds...

Hope this helps!

BTW they don't tolerate ammonia or nitrite - need mature filters and big water changes like 50% a week.
 
All great suggestions but the OP never came back, which usually means they think they're right & we can go jump in a lake.
 
well since the OP doesnt care and wont be back, i was going to make a post asking about this puffer i saw in a pet store. right away when i saw it i thought it was a ceylon. then i look at the sign on the tank and it said "Figure 8 Puffer" in a tank right above GSP's labeled "Green Puffer". all of the tanks in this row were brackish. i thought he looked big for a figure 8 in a store and his colors really made me think he was a ceylon that was mislabeled, or mis sold to the store, which i was a little surprised by because its an aquarium superstore that you can tell they care about their fish and do what they can to maintain and educate themselves, all employees are good and knowledgeable. this puffer did resemble a figure 8 but also had the spots like the GSP in the lower section under the figure 8 markings. he was priced for a figure 8 too which was only like $5. i would like to get him for one of my empty tanks but still not sure of the specific species and information. i was going to attempt to take a picture with my cell phone but he was hanging out in a decoration that had an overhang to it and was shady in there. he was out and about when i came to the tank but after a minute or two he went into his cave looking thing and i couldnt get a good lighting picture
 
Very common--I found 2 Ceylons mixed in with F8s. Great price! Look at my GSP article--exact same care & feeding, only grows bigger, so needs a minimum of 40g ea.
 
yeah i looked them up on the puffer pedia. i have an empty 45, i have two figure 8's already so i know what they look like, and i was just on that fish place's web site and they had a ceylon on there, it looked exactly like the one that i saw in the other store. they seem to be exact to my GSP when i was reading about them. they are cool looking too, im thinking about it :) i already do alot with my marine 75 for my GSP and others so i dont know how i feel about two marine tanks because i wanted to get a congo for one of my other tanks i had one for a while and he was pretty awesome too, i just have to read a little more about them and their main diet. i would definitely do another FW tank for a congo with one of my two empty tanks
 
GSPs & Ceylons should be able to live together (of course they are puffers...). The 75 would be perfect for one of each.
 
i did just sell my smaller one of the two GSP's along with my lemarks angelfish to a friend of mine with a 90 FOWLR that he had cycling for about a month or so with raw fish at first and then added damsels a few weeks later to see how the water would handle it. so he might be a possiblity. my bigger of the two GSP that i kept and love to death and would never get rid of seems to be more lonely without the other GSP, they always seemed to be buddies but the other one would chase him around once in a while and then he would look a little stressed. he never bit fins or anything, the one would chase and nudge him and my bigger puffer would just sit there and let it happen and not do anything back. he only gets excited when i have food rather than all the time when i come up and say hi every day. if i were to get him what would i do, a drip acclimation to my salinity over a couple hours since hes already in brackish water?
 
and the whole reason i got rid of the other two fish is because i changed my mind and i dont want the attention off the big puffer as the king of the tank
