Here is a 6moth update: Everything is doing fine! Seahorses are active as ever, eat, swimming (trying to mate)... They are a LOT more lively than any seahorses I have had in the past.
The only incident that has happened with them is that the tank almost caught on fire about 2 nights ago! Some algae got caugt in the outake from the fuge, and it over flowed, The water spilled down towards the electrical outlets, and got soaked. My dog actually saved the day by waking me up I was fast asleep at 2am when it happened, and she barked at me and i woke up in time to see one of the powerbars spurting purple sparks all over the carpet, and the other one on fire. Today i got new power bars, and i was just Thankful that a the house didnt burn down, and B My seahorses didnt get electricuted!
