New Orleans
I was taking a mental health break this Sunday, at my marsh research site between New Orleans and Slidell, Louisiana. Swooping my aquatic insect net along the bayou bank was producing nothing, so I swooped one last time, and when I sorted through the muck I was very excited to find what appeared to be a tiny little dragon.

My first instinct (tiny dragon) proved to be incorrect, but my impression that it has the head of a seahorse on the body of a tiny snake was much closer to the truth. I've since determined that I found a member of the fish family most closely related to seahorses: a pipefish. To be more precise, my fish is a Gulf pipefish (Syngnathus scovelli), which is apparently the only North American pipefish that spends significant time in fresh water. It is also a particularly difficult fish to keep, according to every reference I've found on the web so far. I'm pretty pumped to have encountered this weird and amazing fish, and I'm enjoying watching it and reading all about it. It is about 4" long, and incredibly slender and delicate-looking. I haven't attempted to sex it, but I'll give that a shot at some point.

I have it alone in a stable 3-gallon freshwater aquarium right now, and it seems to be doing pretty well. I replaced about 1/3 of the aquarium water with mildy saline (3ppt) water from it's native bayou. I'm stocked up on live copepods from its capture site, so I think we're good for the short term. I'll probably observe it for a while, try to get some decent photos, and then release it. When I have photos to share, I'll be sure to post them.
 
Unfortunately it is too small and cryptic for me to get a good shot without moving it to a smaller container, and I'm nervous about stressing it too much, so soon after introducing it into an aquarium. I'll see what I can do, though. Maybe I'll get lucky and catch it napping against the glass.
 
...if only I'd thought ahead and cleaned the glass. Anyway, the pic gets the point across - this is a weird little fish. For size reference, it is just under 3" in length. It is resting against a large whelk shell.

It is acting much feistier now, and swimming around the tank at all depths, rather than clinging to the gravel. I assume this is a good sign, healthwise.

Should keep it and try and get it on blood worms/brine shrimp/live blackworms.

You are planning to release it?
 
Yes, back to where it was collected. I'm concerned about my ability to keep it happy and healthy over the long-term. On the other hand, if it is obviously thriving in the tank, I may put off releasing it back to nature for a while. I'm definitely interested to hear any suggestions/concerns.
 
the point is more or less always the same. If caught and kept, should not be released back...

You should never release a fish from captivity under any circumstances, kill it, or find it home. I would be interested if I was close by. I'm sure lots of others would be too. I have been thinking of getting a pair and trying to breed them. If you keep it try growing daphnia, easy to do and fish love them. I would add some calcium chloride to the water this will allow you to use less salt and keep other fish as well.
 
Ok, well then I'll do my best to keep it healthy. And thanks for the tip on the calcium chloride. I'd love to keep it, I just worry about the difficulty level, relative to my own experience, equipment etc.

Out of curiosity, what is the rationale against releasing a wild specimen back to its capture site? Is it the chance that it may acquire non-native parasites while in captivity?
