The Puffer Forum

The first three pictures of this thread look like P. turgidus to me, the last three could be P. abei and the remaining one is hard to identify, because the snout is not visible (but probably not abei). Here's an illustration that shows the typical two color patterns (depending on mood and breeding) ...

No turgidus. The snout ist too long.

Certainly no Tetraodon duboisi. Probably Pao leiurus or a closely related Asian, long snouted target puffer species.

I agree with Leiodon cutcutia. Freshwater!

@Pufferpunk I don't think the op is looking for the Ocellated Puffer Takifugu ocellatus. I think it's about Leiodon cutcutia (formerly Tetraodon cutcutia), which also has been called ocellated puffer. A quick forum search for cutcutia shows 295 matching posts, some of them with personal experience, ...

Probably L. cutcutia, which can have red lined fins and an ocellus. If you can get any better side pics, feel free to post them.

I'd carry on. When the cysts are excreted there hopefully might not be a next generation.

This looks indeed like a worm cyst. Good job.

I'm not even sure there are nematodes in the sample. Can't see heads or intestines at all. They'd look like this: https://www.apsnet.org/edcenter/K-12/Te ... /step9.jpg Do they move?

The smallest C. irrubeco I have seen looked more like this: https://i.ytimg.com/vi/Pm4OGMf3HVg/mqdefault.jpg with a somewhat reticulated coloration of the darker lateral band just like the adult females.

Probably no female C. lorteti oder female C. irrubesco in my opinion, also no C. imitator. More likely a C. travancoricus like this one: https://rybicky.net/obr/ryby/max/5372.jpg Give it some months to be sure.

Both of these puffers have iridescent eyes. This is no characteristic of M. leiurus.

Yes, M. cochinchinensis stays around 3-4 inches as far as I know.

Fang's puffer M. cochinchinensis in my opinion.

Recently I read a vet's phD on fish narcosis (Geiger, 2007, in German: https://edoc.ub.uni-muenchen.de/6859/1/Geiger_Christina.pdf) in which also various narcotics such as clove oil (eugenol) and MS-222 are compared. While MS-222 is the most often used narcotic for fishes, the author notes advantage...

Seachem states the bond of Prime with ammonia from chloramine or elsewhere is not reversible, but unbound Prime dissipates from your system within 24 hours. Most test kits will give you a false positive measurement for ammonia when ammonia binders (in dechlorinators, water conditioners) are used, be...
