Living here in Panama, I do a modicum of collecting myself, for my own tanks, and I am beginning to realize the difficulties and dangers of collecting in the rainy season, and that just because I want a certain species, doesn't necessarily mean in is to be found.
I started getting serious about collecting after Covid, and although there are as many as about 15 cichlid species known to come from eastern Panama,
I have only found 3 species in those 3 years of collecting trips so far.
I have collected from the Rio Chagres in the central section of the country, to the Rio Ipiti on the east, in the Darien.
In Central Panama, in over a dozen or so trips, I was only able to collect Andinoacara coeruleopunctatus.

It wasn't until I hit the upper reaches of the Rio Pacora, during some intence dry months , that Isthmoheros tuyrense appeared in out nets., I have since found in more easterly rivers.

And in wasn't untill I hit the Rio Mamoni, on the edge of the Darien, that Darienheros calobrense was found.

And there have been a number of trips, where nothing or maybe 1 or 2 fish were caught.
We went to the Rio Mamoni about 2 weeks ago and only caught 1 Sturisomatichthys whip tail cat and 1 Andinioacara .

And that is at a cost for me, of over $200, for the day.
