The fact that you kept a saltwater aquarium so young is exceptional, regardless of WHAT you kept in it.
Yes, there is a lot of controversy on WC vs CB vs TB seahorses, especially since they CAN be tank bred. I have both WC and CB but have never successfully kept tank bred. It seems strange but the tank bred with wild caught parents seem to be the hardest to keep alive through normal life expectancies.
What has kept you from starting a ceph tank? I didn't even know an octopus COULD be kept in a tank until I found TONMO last year. Then it was a matter of affording the life support system ;>). Expecially after we had just started building out our primary reef (which took over a year in the planning and paying for). If my son had not decided to consolidate his tanks, we probably would still just be reading about octopuses. Now if Trapper will just decide we are safe to be around!
