Tiger Barb

The colors really come alive in this fish gallery picture of a Tiger Barb, Puntius tetrazona, by K.Zadorozhny. I kept a school of 6 Tiger Barbs in my first freshwater fish tank. They are a fun fish to watch. I think Tiger Barbs have gotten a bad name of being aggressive fish. Keeping them in a group, does help them avoid getting into trouble.


Originally, I had two regular Tiger Barbs, as you see above. I schooled those with two Green Tiger Barbs, and two Albino Tiger Barbs. Unlike Tetra fish, who generally only school in their own group, ie. Neon Tetras will only school with Neon Tetras, and Black Neon Tetras wil only school with Black Neons; it doesn't matter with Tiger Barbs. Feel free to mix and match these fish. Some considerations to think about if you're looking to add the Tiger Barb to your aquarium:

  • Tiger Barbs are best kept in groups of 5 or more
  • Belongs to the Cyprinidae family
  • Tank conditions most suitable include 73 - 79°F, pH 6.0 - 7.0, KH 4 - 10
  • Maximum size is 3 inches

I kept my Tiger Barbs in a semi-aggressive tank. Other fish included Loaches, Gourami, a couple Plecos, a Redtail Black Shark, and Swordtails. I never saw the Tiger Barbs attack other fish. One thing they would do, which was quite hilarious, is chase each other around the tank. I'm not sure if it was just a game they played, or something else. They wouldn't do it often, but the Tiger barb in the lead would weave in and out of plants, twisting and turning everywhere. The others followed exactly behind. They would also periodically do face to face duels. Again, I'm not sure if this was to determine a leader, or just a game.

For breeding Tiger Barbs; let them pair off. The male Tiger Barb fertilizes the eggs once the female lays them. You'll want to feed the fry brine shrimp after they beome free-swimming. That takes about a week.
I fed my Tiger Barbs flake food and bloodworms. I also spoiled them with Brine shrimp. This will bring out the lovely red color you see in the photo. I highly recommend the Tiger Barb, if you want a fish that's fun to watch. I miss mine.

Blue Tetra

To catch this fast-swimming Blue Tetra, Sakichin had to be quick with the camera. This blue fish, the Boehlkea fredcochui, will grow to only about 1.5 to 2 inches long as an adult. This makes it a great fish to keep in a small aquarium.


It's best to use plenty of plants with the Blue Tetra. They're most comfortable knowing there's a place to hide, and seek cover if needed. The color of the Blue Tetra can best be seen against a dark substrate. If you are just planning your aquarium, you'll want to choose plants, background, and gravel that show your fish off best.

Here are a few things to consider when choosing this fish:

  • Tetra are best kept in groups
  • Belongs to the Characidae family
  • Tank conditions most suitable include 73 - 82°F, pH 6.0 - 8.0
  • Maximum size is 2 inches

The Blue Tetra is an omnivore that will be quite happy eating eats fish flakes or blood worms . Soft acidic water is prefered by this tetra, especially when breeding.

Part of the Characidae family, the tetra has a small adipose fin that makes it different from most other fish. It's believed that the fin is much similar to an appendix in a human. The function is not known.

Stocking the Blue Tetra with fish the same size is best. They would do well with Barbs, Angelfish, Loaches, other Tetras, or non-aggressive fish in the community tank.
