Hi Pete,
Thank you very very much for your long long and very informative answer! I’m not new to keeping dwarfs, I have them roughly for 3 years now and tried different set ups too. My current tank is a 30l tank made by Oase and is named Biorb tube 30l. I would love to upload a picture of it. My current tank has an undergravel Filter and I have real reef rock from aquaculture and black Bali Sand in.

You hear a lot of information about dwarf seahorses one thing you said surprised me, a lot of people recommend to keep them on a Lower temperature too, as high temp will shorten their lifespan they say, so I tried to kept them by 21 degrees. Should I change it to 24 degrees?

Everything worked fine for me apart from the dwarfs getting pregnant so very often. They do get pregnant but since I keep them in a natural tank with sand live rock etc. and I put the pregnant horse in a sterile tank with just a plastic plant it kicks out all of his eggs, very early born baby’s etc. But in the natural tank it is very hard to see the baby dwarfs and I would like to keep them separate for the first two weeks if I can.

Also it always takes some time until they get pregnant again. I’m down to six horses in a thirty litre tank by now.

I feed freshly hatched artemia nauplii and also Copepods. More copepods during the summer though.

Is there any more advice you can give me?

Thank you very much for all your effort and time!

Best wishes,
