Killifish are a really interesting species that definitely deserves to be on this list. Tank Size: 10-20 gallons minimum (species dependant).We love the meshing colorful fish with bright green plants so in our opinion, it’s a match made in heaven! They do well in planted tanks, so if you’re not into aquariums with a lot of vegetation this isn’t the fish for you.

As long as you have the right kind of habitat set up and don’t pair them with incompatible species they’re a breeze to own. Not only are these tropical fish pretty, but they’re also low-maintenance (in general). Dwarf Gourami, Sparkling Gourami, Honey Gourami, and Pearl Gourami are species we recommend to anyone. There are so many different kinds of Gourami, but we have a few favorites. When you combine this with the fact that they spend their time near the surface, you have a nice way to add a vibrant aesthetic that stays out of the way. With bright colors and interesting patterns, these fish stand out in any kind of freshwater tank. Not only are they incredibly unique, but they look great too. They’re peaceful, low-maintenance, and rather small.Īfter Cichlids and Bettas, Gourami are one of the most popular species on this list. These are quite easy fish to keep as well. Our two favorite color variations are the orange body with bright blue dots and yellow body with purple streaks.

The back half of their bodies often have a ton of small spots that evenly cover their body and fins (this varies a bit based on the specimen though). This gives them kind of a “punk rock” look that we love. They usually have a splash of that same color on the front of their dorsal fin, and a dot of it in the middle of their body as well. The first thing you’ll notice about this fish is the long dark streaks that run over their eye.

While a lot of the other species on our list have a lot of their coloration and patterns happening behind their head, the German Blue Ram has stuff going on everywhere! This colorful freshwater fish has one of the more unique patterns out there.
