My LFS has 6 or 7 of these guys for sale, labeled as Black River Puffers (thanks to the PufferPedia, I was able to learn that they're actually palembangensis).
So they're described as "semi lurking." I don't want to get a puffer that I only see at feeding time -- it's the personality of puffers that draws me to them so much. The palembangs at the LFS are extremely active, but it's probably because they're all in a bare tank together with no hiding places.
Just how active are these guys typically? The ones available range from 2" to about 3.5". The smallest one has really caught my eye.
My Puffers: Puffers I have kept: T lineatus T miurus A modestus T biocellatus C valentini C coranata C papuan C lorteti DPs suvattii burrfish T niphobles
Or as a lump on top of a log or cave. Mine spent as much time in view but "resting" as inside it's caves. They do move around a bit, but are not what i would ever label as "active" fish.
My Puffers: 1x GSP (Bolla), 1x m. something. Bought as a leiurus, maybe a turgidus (Tiger), 1x c. irrubesco (Tott(a) aka Houdini) 1x c. salivator (Jack the Ripper), 1x m. cochinchinensis (Hufflepuff - R.I.P.), 2x c. lorteti (Tommy and Tigern = Calvin and Hubbes), 1x m. suvatti (Koseklumpen), 1x m. palembangensis (Dragonfly), 2x t. biocellatus (Koken and Fiken).
super lazy fish lol if you have a big enough tank fahakas are very interactive...but the great thing about palembangs is you can have more than 1 in the same tank
