Rio Niltepec Trimac

  • We are currently upgrading MFK. thanks! -neo
I’m wondering if the different catch locations and slimmer body is indicative of much higher flow rate. Just like the slimmer Breidhori from Rio Salado coming from a higher flow riverine than the typical Breidhori from Presa la Agostura

Tried to Google some of these catch locations and many are not well mapped if even at all. Apparently no google car driving those areas, lol.

There were some pics of the Rio Niltepec in Mexico. Was not a raging river by any means but had some small areas of rapids, areas of shaded tree cover and wide shallow areas. Again from sub adult pics of the trimacs from this area they do seem a bit more elongated than the Rio Naranga trimacs.

Bit of an update. I made the mistake of leaving a Petsmart devil in with the trimacs. At 5 1/2" he knew he was top dog and all the 4" trimac were nipped at and tails were looking rough. I pulled him out, and did a nice big water change to let the trimac heal up. Been feeding "treat" items like Mysis shrimp, brine shrimp and bloodworms to get the guys to fill out. Was a bit concerned because they are a bit lean looking. I will continue to feed this for the first week or so and then work in a high quality pellet food. I keep frozen krill on hand for my other larger fishes and may see if I can get some smaller ones out for the trimac when I thaw out another batch to feed.

Tried something else that Ive never really done with my fish before and that was to add Boyd's Vitachem directly to the fishes water. It is said to help in the healing process. Not sure if this is really the case but I have it on hand so I did it, figured it cant hurt.

Have not seen any major aggression showing among the trimac (yet, lol), there is still that schooling, group mentality to their behavior. Hoping this will go on for a bit till I can decide on who the keepers are. Im tempted to do a tank divider soon especially if aggression starts to become prevalent. For sure there are 3 that I like. The largest has a very outgoing attitude, very nice long fin trailer, nice bright coloration, the second seems to have a decent pattern and seems a bit mellow and chill, the third of course is the one that caught my eye right away with the patterns and teardrop. Interestingly the third one is one of the smallest, he also seems smarter because he manage to be the only one to avoid getting his tail torn by that bigger red devil.

No updated pics... its only been a couple days, so nothing to really show at this point.
