Tank Tinkerer
I bought a Brazilian wild seahorse from LFS in Miami about 4 weeks ago. Everything has been fine for the last 4 weeks. He's in a 10 gallon tank with a mandarinfish, some palys, a small rock of zoas and a ricordea and about 5 lbs of live rock on top of an inch of live sand. The tank ran empty (except the rock and sand) as a "Recovery Room" for 2-3 months before he went in.

He won't eat the brine shrimp I feed the Mandarinfish, so we have been buying freshwater "Ghost" or "Glass" shrimp from the LFS. Sometimes when I order 20-30 shrimp, I get the larger ones (3/4 inch or larger) mixed in with some smaller ones. He won't eat anything larger than the live shrimp that are 1/2 inch or smaller. I haven't found anything else he'll eat. I've thrown Dr. G's rotifers and copepods in the tank but haven't ever seen him eat those (as if I could tell).

I went away on vacation and we ran out of the smaller shrimp. The daughter scooped up any shrimp she saw and dumped them in the tank, so I don't know how long the seahorse has gone without a smaller bite to eat. We returned from vacation on Sunday and went to the LFS that night, but they only had one or 2 smaller ones left. I placed those in the tank but he didn't eat those on Monday. On Tuesday night, I got 40 new shrimp of all sizes and placed 2 in last night. He didn't eat those. Most mornings, before I go to work, I turn on the light and dump 2-3 smaller shrimp in and he usually makes a move toward them. Sometimes I poke the shrimp with a clear plastic rod to get them on the same side of the tank as the seahorse. He's not a big fan of the plastic rod and usually turns away from it. Today, I dumped 3-4 small shrimp in. He seems lifeless, doesn't react to my plastic pipe in his way and didn't make a move toward the glass shrimp.

If he hasn't eaten in 2-3 days, he may be too weak to eat or he may have injured his mouth trying to eat a larger shrimp while we were gone, as a amateur seahorse expert told me. She was a "BIG" seahorse fan and frequented the LFS where I got him. My 22 yr old daughter doesn't care about the aquaria hobby, as much as I do, so in her haste to rush to work or go on a date, she may have skipped a feeding (or 2) or not looked for the smaller shrimp, as they are difficult to see sometimes.

Is there a vet for seahorse? (Just kidding). I can't "pump" shrimp food into him. What can I do? Please help.
 
Have you tried Live adult brine shrimp or half-grown Red cherry shrimp??? They should both be available in your area. BTW...a 10 gallon tank is pretty small for a Reidi Seahorse..it should have at least a 30 gallon.
 
SH often don't recognize Artemia as food...it's not one of their natural foods, this is especially true of WC specimens.

Hopefully, you're enriching the Artemia you're feeding your mandy. Neither of them will survive long-term on "empty" brine shrimp. Also, your tank is WAY too small for either fish, much less the SH. You might want to try a large water change (50%) just to see if that's an issue.

If your SH is WC, it should be treated for parasites (esp. worms) and weaned onto frozen mysis.

If you can't entice the SH with small live ghost shrimp, try getting some live mysis. I'd say that right now, you're on the hairy edge of having to tube feed this fish unless you can get it eating like now. A SH's digestive system can shut down irreversibly in less than a week without food.

I hate to say this, because I'm really not a "SH nut", however, I've kept and bred several over the years: you REALLY should have gotten CB SH, esp. if you're not familiar with weaning them....you wouldn't be where you are now.

LMK, if you need the protocol for tube feeding.
