Guapote Lagunero, aka Rainbow Bass
Rio Indio
Nicaragua
March 2026
Species: Rainbow Bass, Jaguar Cichlid, Machaca, Mojarra
I had been to the Rio Indio Lodge in Nicaragua 13 years prior, in 2013. I split my time between fishing in the ocean for Tarpon and fishing the jungle rivers for Rainbow Bass and other exotics. I had always wanted to go back and just focus on the jungle fishing. I love Tarpon, but there are a lot of places you can catch them. Rainbow Bass are comparatively much rarer, especially the large ones they have here. They have a limited range to begin with and are heavily threatened by overfishing and habitat destruction.
This trip was not purely a fishing trip; my daughter came along and we did some eco touring. Most days I fished in the morning and then came back for lunch and hung out with her in the afternoons and evenings.

The Rio Indio Lodge is a beautiful place built into the jungle in southeastern Nicaragua. To get there, we flew to San Jose, Costa Rica and overnighted in a hotel. The next day, we took a 3 hour car ride followed by a 2 hour boat ride to the lodge. The owner of the lodge, Dr. Alfredo Lopez, accompanied us. He shared many interesting stories of the area and his experiences in the 20 years he had run the lodge. Sadly, Covid, political unrest in Nicaragua, and a hurricane several years back had put a damper on tourism. The lodge was clearly built to hold 20-30 guests at a time, but when we arrived we were the only ones there. Later in the week a Canadian couple arrived, but they were the only tourists we saw the whole time.

The fishing options at the Rio Indio were as follows – fishing the ocean for Tarpon, casting and trolling the river mouths for Snook, or fishing the jungle rivers for Rainbow Bass (locally called Guapote Lagunero), Machaca, and Mojarras. I spent nearly all of my time on the last option, although I did spend a couple hours casting for Snook and only managed 1 4lber which made excellent ceviche.
The Rainbow Bass fishing involved casting spinnerbaits and crankbaits in very tight to structure. One of my favorite types of fishing. A cast that strayed more than a foot from the target never resulted in a hit. The area had received an unseasonable amount of rain during the month, making the waters high and muddy, which was not great for the fishing. During high water times, the fish head into the flooded jungle to exploit new food sources. However, once I dialed in my casting I was able to score big bass on every morning trip if I stuck to it.

As soon as they get hooked, Rainbow Bass head straight back to the cover where they live. On my last trip to this area I lost some bruisers due to snapped lines, but this time I came prepared with sturdy 25lb leaders and locked-down drags. As a result, I did not lose any fish in the snags. Despite my best efforts, I could not stop a couple of big bass from getting back into the sticks, but somehow I got them all out. One of them appeared totally stuck, but I slacked off my line and waited a couple of minutes and it swam out and I was able to land it.

The beautiful jungle scenery really enhanced the fishing experience. A variety of birds flitted about, howler monkeys called from the trees, and an occasional startled crocodile or lizard would flee into the water. My daughter and I did several jungle hikes and did not see quite as much wildlife as we expected. However, we did see a wide variety of birds (including a toucan), crocs, poison dart and other frogs, monkeys, and lots of lizards. We also saw two venomous snakes, including a Fer de Lance Viper that my daughter accidentally got far too close to when she took a couple steps off the trail. It was very small, just over a foot long, and I don’t think it could have bitten through her sturdy rubber boots, but still worried me. She was better about staying on the trail after that.

The Rio Indio Lodge had several large aquariums that were largely empty, so we spent a couple of hours catching small fish with sabikis and small rubber jigs to put in them. We got 4 Jaguar Cichlids, 8 Mayan Cichlids, and a large number of small baitfish they call Sardinas down there. The Cichlids thinned out the Sardinas right away, so we went out and got more.

Occasionally I took a break from the Rainbow Bass fishing and fished for some of the smaller species with ultralight tackle. I landed a good number of Machacas, an acrobatic aggressive silver fish that was abundant in some of the waterways. They liked to sit in the shade under trees and eat fruits and other things that fell in the water. I fished a minijig under a bobber some of the time, and many times they struck at the bobber thinking it was a fruit.

Mojarras, a colorful Bluegill-like panfish, were also abundant. I identified two species – the Black Belt Cichlid and the Mayan Cichlid. Both struck lures meant for the bass and rarely got hooked. However, a smaller minijig really worked well for them.

On the last morning, I decided to break out my fly rod and had an absolute ball casting poppers on my 5wt. I think I caught almost every species in the river, topped off by my biggest Machaca of the week which really put up a tussle on that rod. I kind of wished I had spent more time doing that, but I really enjoy hunting big Rainbow Bass as well so it was a tough call.

For people thinking about visiting the area, I highly recommend bringing your own tackle. The lodge had tackle, but it was pretty dicey. You also have to be willing to rough it a little bit; the lodge had AC in the rooms but often did not have hot water. I asked for shampoo and received this flower that I was told I could squeeze into my hair, although they did scrounge up a bottle of Head and Shoulders a couple days later from a nearby town. Mosquitoes were around in the dining room during meals and really bad out in the jungle when hiking. However, I didn’t have to deal with them at all when in the boat. Food was excellent; my normally picky daughter eagerly ate every meal.
If you want to concentrate on Tarpon, you need a good weather window to get out of the river mouth. It was too rough to get out the whole time we were there. I was really glad I wasn’t planning to fish for Tarpon. The calmest time is September/October, although the prior trip in April we got out into the ocean every day.
In total, I caught around 45 Rainbow and Tiger Bass, 15 Machacas, and a large number of Mojarras. I fished a lot more casually than I usually do so that I could spend time with my daughter. All but one of the Rainbow Bass spots I fished involved long runs, from 1.5 to over 2 hours, so a lot of time was spent just running to and from spots. If I were to go back and concentrate more on fishing, I definitely would have fished whole days and packed a lunch to maximize fishing time. That would have made for some extremely long and hot days, but I think that would have significantly increased my catches. However, I was more than happy with the trip overall and caught more big Rainbow Bass than I had expected.
