MrGibson Posted March 2 Share Posted March 2 Hey y’all. Tonight while sitting in front of my medaka grow out tank I noticed a little fish along the bottom that I didn’t put in there. I was only able to get some pretty terrible pictures of it. The current theory is it’s maybe a puffer if some sort based on its movement. It stayed near the bottom and slowly moved from spot to spot while moving its eyes in the orbits and picking food off the bottom. It’s hard to tell because it’s so small but it appeared to not be using its tail to swim and was moving very slowly and smoothly. I’m assuming this fish had to have come in as an egg on a plant or something and hatched out in my tank. I’ll attach the pictures I was able to get even though they suck in hopes it can inform some guesses. I’m thinking I may camp out in front of the tank with my dslr and a macro lens for a few hours this weekend to get a better look. If I’m able to I’ll update this thread. @mountaintoppufferkeeper I know you keep and breed some puffers. Any ideas? thanks y’all! 2 2 Link to comment Share on other sites More sharing options...
mountaintoppufferkeeper Posted March 2 Share Posted March 2 Cool. Congrats. Its tough to see in stills. I do a video on the phone and make it a gif for the short videos here. Spotted congo for comparison And pao palustris basically tiny foodbellys with eyes from very early on I had a mystery flag fish fry before that made it through a sump overflow rack and multiple predators until discovered around that size. It probably went through the pump at least once as egg and new fry. Tracking that down now will update with that gif once found 7 1 Link to comment Share on other sites More sharing options...

I’m definitely going to try for some video this weekend. Im not certain it’s a puffer but I’m having trouble thinking of anything else that moves like that. I’ve got a new light coming Monday as well so that may help brighten things up for better visibility. I’d say it’s probably around a half inch or so right now but that’s really a guess based on the few glimpse I got of it. I’ll be sure to update if I get any video thanks 🙂 2 Link to comment Share on other sites More sharing options...

Odd Duck Posted March 2 Share Posted March 2 Here’s some pea puffer fry for comparison starting younger. 3 Link to comment Share on other sites More sharing options...
MrGibson Posted March 3 Author Share Posted March 3 Update! It reappeared! I’ll work on getting a gif posted 2 Link to comment Share on other sites More sharing options...
MrGibson Posted March 3 Author Share Posted March 3 I gave up on a gif. Here’s a link to a video. any ideas? The movement of the mouth has me thinking it’s not a puffer. side note, does anyone know the term for fish mouths that extend forward like that? Just curious 1 Link to comment Share on other sites More sharing options...
MrGibson Posted March 3 Author Share Posted March 3 @Fish Folki know you’ve worked with a good number of species. You ever seen a fry like this? 2 Link to comment Share on other sites More sharing options...
Fish Folk Posted March 4 Share Posted March 4 I’m not sure. I thought Jordanella floridae at first glance… maybe a little male… but that doesn’t seem right. To my eye, the Dorsal + Caudal fin pronouncement seems to preclude Puffer… but I’ve never raised juvenile Puffers. 3 Link to comment Share on other sites More sharing options...
Colu Posted March 4 Share Posted March 4 I was going to say Florida flag fish @Fish Folk 3 Link to comment Share on other sites More sharing options...

Flag fish crossed my mind as well, largely from @mountaintoppufferkeeper’s post, but I’m not really sure. I may try to figure out who I’ve bought plants from and see what they think. I’d agree on it not being a puffer at this point.

MrGibson Posted March 7 Author Share Posted March 7 Looking further into this tonight I’m thinking I can maybe say it’s some kind of pupfish, similar to flag fish. The only issue I’m seeing is that most pupfish have truncated caudal fins whereas this appears to have a rounded caudal fin. I guess it’s possible that shape changes with age maybe? so far I think the closest match I’ve gotten is desert pupfish but I don’t believe those are commonly kept, and again the caudal fin is off. And thus the rabbit hole goes deeper. 2 Link to comment Share on other sites More sharing options...
Odd Duck Posted March 7 Share Posted March 7 Definitely doesn’t move like a puffer although I can certainly see why you thought it might have been initially. Every puffer species I’ve ever seen closes the tail a lot and uses it to turn in place vs mostly using their pectoral fins to turn (although they will do that, too). But they usually have some color in their tails and flick them the tiniest bit to rotate on the spot. They will curl their bodies right up when they spin in place. Plus the mouth isn’t right. No guesses from me although I think you’re on the right track with pupfish / flag fish body type. 1 Link to comment Share on other sites More sharing options...

I think at this point the best way to narrow down the ID is to grow it out lol 1 Link to comment Share on other sites More sharing options...
