dwarf seahorses and regular seahorses?

There is no cleanup crew that can handle normal seahorses in a 10g tank.
If you think about it, the snails will eat the leftover food and produce their own waste, then the micro life consume the waste of the snails, and eventually all that waste ends up as dissolved orgainics, nitrates, and phosphates, that pollute the water and fuel algae growth.
With the larger tanks, the end result is diluted more than the small tank and would take longer to be a problem.
Buy a 29g and you have no problem.
Don't buy it and stick to H. Zosterae dwarfs.

 

yea im gonna do a mantis tank instead. im not ready for seahorses yet.
