A 32-gallon biocube is about 22 inches tall, which is sufficient height for a seahorse setup. Water quality is much more important than water depth when it comes to keeping seahorses successfully, and as experienced marine aquarists, you and your husband already know all about how to maintain optimum water quality.
And it’s good that you are doing preliminary research and have ordered some guidebooks that discuss the care and keeping of seahorses. I believe the Ocean Rider Seahorse Training Manual will be far more helpful to you in that regard, however, than any hobby book. If you contact me off list at the following e-mail address, I will be happy to send you your free copy of the comprehensive seahorse training manual and to go through all of the lessons in the training program with you:
And I will also send you an article devoted to the subject of seahorses in the reef tank, which will explain which corals are safe to keep with seahorses and which live corals should be avoided in an aquarium with these amazing aquatic equines.
Just send me a brief e-mail indicating your interest in the seahorse training and we can get started right away, Things With Wings!
