Would a black sailfin blenny be good with a seahorse?

Unfortunately the odds are that you won't fine someone that has tried that particular fish on this forum.
Best to go by the "orgs" tankmate list and if it is acceptable there the odds should be in your favour.
Of course, there are fish not recommended that sometimes work out, just as some that ARE recommended do NOT work out.
Just like reef fish compatibility, no 100% guarantee.

ok

I would say no.... It would out-compete for food (most blennies are opportunistic feeders). Also, I would just hate to see it start trying to scrape algae off of a seahorse!

mk then im not gunna get one, also you said blenny, does that mean a scooter blenny wont work?

[SeaHorse_Fanatic]

Scooter blennies have tiny mouths, eat very daintily and are more like Mandarin gobies than Lawnmower or Black Sailfin blennies.

Scooters would be fine, if it will eat frzn. foods.

You should do alot of research on seahorses. They are not that easy to keep. You have alot of posts about what fish are compatible and a wish list of corals you are looking for. I don't know how much expereince you have or the system you own, but some of the more expereinced people don't have some of the listed corals on your list. Seahorses can be stung very easy by some corals listed. Can you describe your system and I'm sure other members will help you out with what you need to successfully keep seahorses. It will save the well being of the seahorses and alot of time and money. In my opinion they are kind of boring if your a real tank watcher.

Well first of all, beauty is in the eyes of the beholder. Otherwise, our tanks would probably all look the same.
Stinging corals are a problem with seahorses and so it's important to keep the TANKMATES GUIDE in mind when planning your seahorse tank.
Keep in mind also, the requirements needed for your tankmates selection as some don't handle lower temperatures or need extremely high lighting which can cause temperature issues.
Some of us don't keep tankmates of any kind, or at least keep it very minimal as the fewer tankmates, the less the chances of introducing pathogens that can affect your seahorses. I don't even keep live plants myself.
Anything you can do to minimalize problems increases your chances of success. Even doing all that you can does not guarantee success though so keep that in mind.
You have to be more diligent about everything especially husbandry to give yourself the best chances.
