Freshwater Pipefish


Recommended Posts

20211006_134931.jpg.a8985ffe17769086fd16133e4636c761.jpgI thought that maybe some people might be interested to see my freshwater pipefish Doryichthys martensii.

I'd also be interested to hear from anyone keeping these or similar species. Has anyone bred them? Apparently it's not too difficult with some species. They're like sea horses so the male takes the eggs from the female and holds them in a pouch until they hatch.

These guys are also known as long shouted Pipefish and they come from Southeast Asia. They're true freshwater fish unlike many that are estuarine or fully saltwater. 


I have 5 in a 50l tank because they enjoy company. They're not quite full grown yet (assuming 15cm full size) so I might upgrade them but for now the tank works well because they don't move much or fast and they require mostly live small foods. The smaller tank size makes it easier to get the food to them. I have neocaridina shrimp and amano shrimp with them as an extra food source. They will pick eggs straight off the amano shrimp, it's quite funny to see. 

Here's a video of them being useless at hunting daphnia. I like how they move their eyes. It reminds me of puffer fish.

Wow, those are neat! It's funny to see how the shrimp boldly walk up.

The blue dream shrimp ride them occasionally!

Do they use their tails like seahorses to hold on to things?

They do. Often they sit in the plants in a vertical position and hold on with their tail.

do you need to have a constant supply of live food in there tank like you do with seahorses

They can go overnight or a few hours in the day without food so they don't need a constant supply but very regular feeding is required because like seahorses, they have no fat reserves. They do actually eat frozen cyclops which is handy as a backup food.

Kept a group of 4 of these last year. Awesome fish. Just found the daily feeding of live baby brine to be bit much for me. I did get them on frozen daphnia and cyclops though. Certainly a fish I might reconsider down the road. Be very curios on how your breeding project goes.

They're definitely on the high maintenance end with their food needs. It will be nerve wracking trying to keep the fry fed if they do ever breed.
