Seahorse Tankmates Guide - Part I: Fish

[Lionfish Lair]

It's like a Foxface, you know they have a nasty venomous sting, but the odds of you getting hit are small. A Tang's scalpel can get ya, put again the odds of that happening are small. In my 20 years in the hobby, I only know 1 person personally, who has been hit by either (and he was actually hit by both... aquarium maintenance job). Scorps/lions are the nicest fish and literally come sit in our hands and on each other. I've often wondered why they don't sting each other accidently when they are all begging for food in a clump with their spines banging off each other, but it doesn't happen. I'm not sure why... BUT, I'm going to change the rating to a 1 to bring attention to the issue.

And just cause it's cute.... I call this one "Brown Chicken. Brown Cow."

I spend a lot of time on your site, because deep down I want a fuzzy dwarf lion and a fu manchu. When I see your posts I just want them more.

I had 2 Fuzzies, a Fu, a Sphex and a Radiata lion in a 100g along with other scorps. It was my favorite tank. The fuzzy is a fantastic first lion and the Fu is a perfect tankmate for it.

Thanks! I'm giving more thought into them for my next build! Maybe no seahorses at all then and just go lions!

 

[mgoesma]

Love this.

 

[vlangel]

Love this.

I enjoyed this too.

 

[Rybren]

I know that this is an older thread, but would tankmates for pipefish be similar?

 

[Rybren]

Just thought I'd give this a little BUMP

 

[H2Ocorals]

why are they not compatible with so many other fish. Clownfish are not very harmful, do the seahoreses get defensive? or the clownfish?

Sorry none of us saw this but in general most pipefish do have similar needs as seahorses and similar vulnerabilities, so it is safer going with similar tankmates. I do read of folks having fairly good luck with them in mixed reefs with a mixture of fish however.

Seahorses are more easily stressed than other fish and they never stick up for themselves with other fish. Since fish in tanks seem to operate on a hierarchy or pecking order, seahorses end up on the bottom. They can be with fish who are also none confrontational but do not deal well with fish that do participate in the heirarchy, like clownfish. Since this is stressful to seahorses and they get sick easy anyway, its best not to put them in situations like this.

Thanks. I suspected as much. Unfortunately, I woke up a couple of mornings ago to find both of my dragonface pipes dead. They had been eating well and had shown no signs of distress. I do still have a bluestripe, but it tends to keep to the back of the tank when the lights are on.

 

[Devaji]

I would like to know how many ppl are keeping butterfly fish with SH they are #2 on the list so should do well.

if that is so, that would make we very happy.
the tank I am thinking would be a 105 DT with a 35ish gal sump total volume is 140 US gal.
thinking 6 SH and maybe 3 butterfly fish
thoughts?

oh and is there an invert, safe list?

 

[locito277]

I was wondering if a pair of Madagascar crouching gobies would be ok tankmates for seahorses in a 120 gallon reef? I know they have poisonous spines but are unlikely to come in contact with the fish. Anyone have any experience? Tanks 120 gallons with 7 garden eels, 9 ponies, 2 blue line pipefish, midnight angel, yellow tang, blenny, cleaner goby, possum wrasse, pair of fathead anthias, and a pair of percs. There are about 6 spiked fin gobies, weird inverts. Tanks been running about 2 years. Countless cocoworms and feather dusters. Gaudy clown crabs and a pistol shrimp. Zanzibar, blue Coral banded and golden banded shrimp and hermits Of different kinds. If the Coral Croucher a would endanger the ponies I’ll put them in my other aquariums
Instead. Sorry for rambling

 

[Devaji]

I cant offer any help but I would love to see your tank! have a build thread or YT vids?

So, what's in a number? It's pretty safe to say those with the 0, 1 and 2 rating are safe to add to your seahorse tank, provided individual needs of both fish are met.

A rating of 3 is pushing the envelope and may or may not work based on the individual personality of the particular fish you are trying to introduce. Please have alternative plans to house the tankmate, should a problem arise. There are plenty of fish in the 0-2 category, so it's really best to leave these be.

Those fish with a rating of 4 have no business being housed with a seahorse, IMO.


This is a rework of a guide from some years ago on another site that my friend Kevin and I put together on Seahorse.org. Many pictures are the same, so I wanted to explain that they are mine and not lifted from the other site (in case you run across the other one). I changed the rating system, so that it was less subjective. Back then I hated the idea of tankmates and fought it tooth and nail. LOL!
