They are difficult and require much care. I didn't believe you when you said the seahorses would eat the crabs, but after looking it up it's true. Surprising since their mouths are so small, and they seem so...peaceful
It's a home office so it's an easily accessible tank. If it was in a workplace, I would agree with you that they wouldn't get the attention/care they needed.
I've already researched loads. I would not go into this adventure blindfolded. Seahorse.org has been a very helpful source for me, but that site looks great too. There's still a ton left to learn though.
I was actually ordered the 2 seahorses from Seahorse Source a couple days ago and they would have arrived today, but I put off my order for a couple weeks after talking to Dan, the owner. He was very helpful in supplying useful information. He was explaining to me that it's best to have a 30+ gallon tank for seahorses, not so much the size they get when mature, but that they need to be in a tank with a lot of filtration and a skimmer. With my 20 gallon, I only had a HOB
filter for filtration. Also, low flow for a seahorse tank is a myth. In the wild, there are places where seahorses thrive where the current is very strong. Also if there's a lot of waste in a seahorse tank, it makes sense that having a strong enough current to keep that debris suspended.
In his experience when he put seahorses in a tank with much stronger flow that the seahorses became much more active.
This is my 3rd saltwater I'm setting up, so I do have some experience. It's not like I've always wanted seahorses and I'll throw some in the tank and food and hope they'll do well. I know the time and care they require and am prepared for that
. Thanks for the advice.
