hes come home into a well cycled tank,ph about 6.8-7.0,temp at about 80 degrees C,with a high powered filter which should cope with the puffer waste I hope,I've previously kept dwarf puffers*fresh* and figure eights*which I now know should have been brackish sadly the store sold them as freshwater,although they did live for about 4 years in fresh,not sure what their lifespan would be in brackish* before so i know a little about the species but not much about the bigger ones.
His belly has gone almost black,I know in figure eights this a sign of illness or stress,is this also the case with ceylons?,he also puffed a little when the guy caught him,he has deflated now and has been swimming around in puffer fashion checking things out,he has also taken some food,hes been home about 12 hours and i just fed him a bit of cockle to see if he was stressed or not,with my figure eights,they wouldn't eat if stressed,he took it and shredded it up,hes hanging out near the bubbles in the tank behind some big rock.
So how does his care differ from the smaller puffers what size tank should he be in,what sort of decoration,I have in there at the moment,bog wood,tufu rock and some real plants,is this going to be suitable,also I now have read he is a brackish puffer so how do I go about changing the water,the fish place told me to stick some aquatic salt in the tank as thats what he was in at the store? I thought brackish had to be marine salt? Is there any big dos or don'ts for this guy,I'd appreciate any advice or links anyone can give me,I'm just off to search the net for ceylon's,anyway sorry about the really long post and thanks
