I have two female kuda seahorses in a 10 gallon tank. I'm looking to get two males so i must get a bigger tank. Would an oceanic biocube work and does it come with everything needed? What do i need to get if not?
I have no experience with that aquarium as I use normal tanks, but I've seen posts on seahorse.org about them and the biggest drawbacks that I can remember seeing is the water temperatures are very difficult to keep at the recommended range of 68° to 74°F, and, it has poor gas exchange at the water's surface because of being completely enclosed.
Why not just get a regular 30g tank and use that?
Although, maybe if you had the money and space, you could hook up a chiller? I don't see why not! I mean my seahorses need a chiller anyway to keep the temperatures stable enough, even in a 'non-all-in-one' tank
