Here is a list of some of the most rewarding and interactive FW fish. I’m sticking to ones that either don’t cost an arm and a leg or don’t have extremely special needs. This is based on my own knowledge and personal experience, as there are so many:
- Convict cichlid or any Amatitlania cichlids
- Any Amphilophus cichlid
- Blood parrot cichlid
- Flowerhorn cichlid
- Oscar cichlid
- Blue Acara cichlid
- Dovii cichlid
- Chocolate cichlid
- Jaguar cichlid
- Severum cichlid
- Peacock bass
*This is a select few cichlids, the list just goes on, they’re practically dogs.
- Giant gourami
- Betta fish
- Red wolf fish
- Dwarf puffer fish (and pretty much every puffer, but obviously SW puffers are the same deal)
- Black piranha
- Any pacu species
- Arowana
- Goldfish
- Sunfish (basically cold water cichlids)
- Bichirs
- Spiny eels
- Knifefish
- Gymnothorax polyuranedon
- Pleco
- Gudgeon
Fish that may not be personable but are awesome and/or beautiful:
- Banded leporinus (x1000)
- Exodon tetra
- Red bellied piranha
- Redtail Barracuda
- Sailfin tetra
- Loaches
- Raphael catfish
- Redtail catfish (and other large cats)
- Corydoras
- Rainbowfish
- Livebearers (a lot more fun than they seem)
- Killifish
Some fish that are rare, expensive, or expert, that I’m not as acquainted or experienced with, but do know about:
- Aimara wolfish
- Snakehead fish (illegal in US, sadly)
- Asian arowana (same idea as snakehead)
- Rays
- Gulper catfish
- Pipefish
- Tigerfish
I don’t doubt that SW has its fair share of amazing fish. Color-wise, I’ll always go for SW, but for personality, and a true “wet-pet”, FW is more my cup of tea. There are certainly plenty of personable tangs, angels, and of course, damsels, but as far as commonplace fish goes, I see more options in FW, especially for those practical and non-expensive to keep and observe. As far as scaping goes, much like a reef, natural is always better. Only when they aren’t made up of plastic or fake decor is it truly a masterpiece. Obviously, SW would win in the fish category with sharks and giant groupers, but as far as practical fishkeeping goes, FW seems to offer more affordable and maintainable options. That’s just my two cents, being a long time freshwater guy, and relatively new reefer.
