Marilyna darwinii profile

Post by UncleFugu »

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

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?

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.

Where do I attach the pics?

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.
