S.O.S...MY OCELLATUS NOT EATING

  • We are currently upgrading MFK. thanks! -neo
Good news.. this monster starts taking live shrimps..
wondering why this forum so many pro, but no one can helps me to ID this monster..
 
LoL well i guess thats what puffers look like when they should have been converted to brackish and kept in freshwater for their life...

The high mortality is almost certainly because people keep them as tropical freshwater fish. They are, in fact, subtropical estuarine fish. The best results (i.e., where people have kept them and they are still alive) seem to correspond with their ecology in the wild; specifically:

Moderate salinity (~1.010)
Lots of oxygen (use a spray bar or venturi)
Low temperature (~15-18 C)

Raising the salinity to marine levels decreases the dissolved oxygen, as does raising the water temperature. Like all subtropical fish, they are sensitive to low oxygen levels, especially where high temperatures raise their metabolism.

Takifugu species are routinely kept in labs as well as being farmed, so there's no reason to assume that this species can't be kept in captivity. It's simply aquarists haven't realised that these fish need very specific conditions.
 
If you do indeed have the ocellatus, I doubt anyone here has ever seen one captured at that size. I have a small one. Mose of the even long-term pufferkeeping experts have problems keeping this particular fugu species alive in captivity longer than 4 months.

yet they are sold and killed all day at my lfs ..... That puffer is f-ed if hes been kept in freshwater that long, you need to start converting to brackish, or you will only add to the damage done to his poor life :(

Its like trying to ID any fish, when its really beaten up, in bad condition and with only a certain few angels its hard to ID... kinda like trying to ID a pleco from one shot if its completely beaten up... it can be done, but very difficult to be sure which species it actually is...

Try and maybe get some proper side shots of the fish as well and then throw it up on the Puffer Forum... i'm almost 100% sure some one there will be able to give you a definite answer as to exactly what species you got there... since there are a lot of PUFFER Pro's there...
 
Well, if you won't go to TPF, I'll bring the ID expert here. ;)

ok great...later i'll get some more side shots of this so called OCELLATUS...
after d proper measurement...now confirmed d total length is 37cm...
 
Here ya go, "Takifugu obscurus, a close relative to T. ocellatus, but significantly bigger and heavier. Up to 40 cm and more than 10times more biomass than T. ocellatus." This fish belongs in SW.
 
More info on this species from TPF:
Very oxygen demanding. Lives in SW and breeds in freshwater to brackish water (in contrast to T. nigroviridis, who's just said to do so, but acts the opposite way). It can be kept in freshwater, as long as it is hard, clean and not very warm (subtropical). Among all marine puffers this one has the highest tolerance for low salinity known so far. Can mostly be kept in groups without trouble and will eat usual puffer food such as clams, mussels, larger snails, crabs, shrimps. Needs lots and lots of space for a puffer of this size (much more than a Arothron of similar size) and likes to swim. As a side note, this fish is bred and farmed in large numbers in China and Korea.

To sum it ip: Much space, minimum nitrates, high oxygen, lower temperatures than tropical tanks... did I mention much space?

Here's a nice study on this species:

and another one:

I believe water quality (low pollution, high oxygen) is more important than salinity. Personally, I'd keep it in marine, that's the most natural way and therefore most promising with regard to long term (>10 years) care. After all it's a marine fish most of its life.

From reading that 1st link, says they tolerate FW but doesn't seem for very long, nor would I suggest keeping one in FW indefinitely.
