has anyone any experience with the sailfin tetra? can anyone tell me exactly where they are found, or what fish they are often found with, or has anyone here ever kept or bred them?
i am on the lookout for a few at the moment and would appreciate any advice or help from any of the fish keepers on here, ...... particularly you larry!!!! sorry for putting you on the spot, but your advice in the past on a number of species has sent me in the right direction to crack their care in captivity
regards
joe

My experience with these is limited to about 1 week. I just got a shipment of 60 of them in. Very cool fish. They are really shy and will dart under the driftwood in a heartbeat.

I'm feeding these blackworms and will eventually try prepared foods. My first concern is getting them eating and then weaning them onto other foods.

They come from Peru but I don't have an exact collection location on these. They are a cave spawning tetra that I'm told behaves more like a dwarf cicihlid when spawning. I hope to keep a pair or two for myself and see if I cannot get them to spawn.

If your interested in getting some email me at bev@theamazonbasement.com.

i would love to take some from you Bev, but i am on the other side of the world and i think the shipping would out of my price range!!!!!!
keep us updated with how you get on with them though, i would be very interested in hearing your experiences with them, they pop up here in ireland occasionally, but i have not been quick enough to grab a few yet!

Aww geeezz. Sorry. I didn't even think to look where you are from.

I'm planning on keeping some to try to get them to spawn. Just tonight they started to settle down and not scatter when I went to look in the tank.

I'll post an update if I'm fortunate enough to get them to spawn.

as luck would have it i just managed to pick up a couple a few days ago,
live foods like glass worm ad daphina taken on the first day, after that they moved on to tetra prima and tetra crisps pretty quickly, though only when sinking in the tank,, they show no interest once it hits the bottom so a couple of whip tails and shrimp are in the tank with them to mop up any they do not eat.

These are one of the species that I have never kept so all I know is what I have read about them.

The closeat I have come to them is my attempts to keep and breed Black Darter Tetras Poeciliocharax weitzmani and I never did breed them.

since i posted last on them they are eating me out of house and home!
eating from top bottom and middle of the tank, and are growing fast, filling out and the males are coloring up nicely.
i am feeding them tetra crisps, tetra prima, ocean nutrition discus flake, and for live food cherry shrimp, glass worms, daphnia, blood worm,earth worms and any flies, beetles bugs i happen to catch in the pond outside.
any damaged fins scales etc have since healed up and they are in pretty good shape now
here is a pic of a male, you can see his 'cave' in the background

and one of the females

they are fascinating fish to watch hunt down their prey

here is a video of the sailfins in the previous pictures, it is 9 minutes long but I think it is really worth watching, make yourself a cup of tea and sit back and try watch all of it.
click the picture to get it to start, tks

tks I am actually really delighted with myself for catching this on video, I would love to be able to view parts of the video in slow motion, but my computer skills are really lacking in the tech department!

I'm pretty sure I had these fish in my nets many times, but I related it more to Genus Copeina than to Crenuchus, I was not familiar with the genus, or maybe never paid much attention to it... or maybe it was a similar species. They look like a nice and uncommon addition to a South American habitat tank.

I bet you did Crenuchus spilurus is actually a very widespread fish found throughout most slow moving waters of the amazon river system, but it seems to come up for sale with little regularity, Aquarium Glaser was recently offering two new undescribed species for sale, one a very nice red form, overall they are pretty peaceful and do not bother other fish but last year I spotted one male putting a male Apisto baenchi in it place with such a swift and aggressive charge that the Apisto was actually stunned
