Hahahaha thanks bud! So when is this trip of yours?? Make sure to take tons of photos if you can, id love to get some up close shots of natural habitats for my chocolates and parrots! I hope you find some awesome fish for your collecting mate!
hire a local fisherman to help. last i saw though i could be wrong you could only bring back 6 fish with you. one of the members of my club has a fish farm down there and always brings stuff back with him. if fish and game have to come out you get charged for that as well.
Nannoptopoma would be highest on my list, either N. sternoptychum or N.species "Peru". Very neat little Cats that occasionally come in as contaminants in bags of Otos.
Currently, I have a tank I can borrow when I get back, but I need a permanent solution. Does anybody around me know of a tank, preferably 30 gallons, for sale? Thanks.
