Marilyna darwinii
Common Name: None (Rare Species - I believe I am the only person on the forum who keeps one)
Other Names: Sphoeroides darwinii, Tetraodon darwinii, Marylina pleurosticta
Family: Tetraodontidae
Distribution: From Pilbara coast of Australia around north coast to northern New South Wales; also in Papua New Guinea. Large population density in Darwin Harbour.
Water Parameters: Temp: 23-26C (74-80F); pH 7.4-8.4 Salinity - Brackish - Marine. The best bet is to give it the same salinity as where you caught it.
Personality/Temperament: A somewhat active fish, M. darwinii is a good community specimen, but wild-caught specimens (Unfortunately they are not bred on farms because of low demand) often do not survive. Of the three I have caught only one has survived for about 10 weeks. They are strange for puffers - as mentioned above they are a good community fish, and the only puffer I know that will not attack crustaceans, provided the latter are at least 3cm (1 inch long. They are peaceful with other species of puffers, fish and large invertebrates.
Max. size: 9.5 cm (3.75 inches) There have been unconfirmed reports of fish over 10 cm.
Estimated lifespan: Unknown ~ 6-10 years?
Sexual Dimorphism: Unknown.
Diet: Frozen bloodworms, crustacean meat. will not attack live crustaceans or fish. Will eat sea fans, fleshy plants and corals. Has rarely accepted live snails.
Care: Not much is known about its care. I am pioneering into it and have found that it requires large tanks of at least 70g. Send me a personal message if you have kept one.
Minimum Tank Size: 70g (140L)
FishBase code: Madar_u0

Re: Tetraodon darwinii profile
Pics are needed to go with it.
If you could also add what salinity it is kept at, full marine etc...
Is there a reference for the information you got for sexing them?

Re: Tetraodon darwinii profile
I'd change the name to Marilyna darwinii (as shown by fishbase), because that is the valid genus. There are several characters much different to Tetraodon.
Give a man a fish, and he'll eat for a day. Give a fish a man, and he'll eat for weeks.

I worked the sexing out myself from days of study of them.Hilly wrote:Pics are needed to go with it.

Where do I attach the pics?

Re: Marilyna darwinii profile
You can attach pics by creating a gallery.
We cannot put information like that in.
The sexing will have to remain out of the profile for now. Unless you get a single pair of what you think are male and female to breed the sexing cannot be confirmed.
