would a seahorse live in a 5 gallon tank if the water quality is perfect all the time
From the little research I have done seahorses aren't the easiest to keep. They need stable temperatures which means a heater and a chiller.
If you are looking for something for a small nano tank that is different what about pom pom crab and a few sexy shrimp?
