Answer: Any tropical fish that likes warm unfiltered water, is not nippy and does not have long fins. Bettas will also respond well to snails, or shrimp. In general, the best betta friends (betta fish tank mates) you can find are slow moving bottom dwellers.

4. Can I keep my betta fish with goldfish?

Answer: No. Goldfish require large filtered tanks and very cold water – completely the wrong conditions for a healthy betta fish.

5. Do betta fish sleep?

Betta fish care FAQ Answer: Yes, when betta fish are sleeping they usually just float in a very still part of the tank – appearing to be frozen.

6. Where can I find betta fish for sale?

Answer: Here! Be careful where you buy betta fish as they can have a very limited lifespan if kept under the wrong conditions. Our experts keep our live betta fish under optimal conditions. Buy betta fish from and your healthy betta fish will be at your door before you know it.

7. What do I need to know about breeding betas?

Answer: Bettas need to be conditioned for breeding before you put them in contact with each other. This step can usually be accomplished within a few weeks. The fish should both be put on a diet of live blackworms and/or brine shrimp. Over this period you’ll notice that the female betta fish gets a little fatter (a sign that she’s full of eggs).

Introducing the male and female to each other too soon can result in them fighting instead of mating. They need to see each other to acclimate themselves for a few days first. The best way to do this is with a divided tanks, such as the Marina Betta Barracks. You’ll also notice bubbles at the top of the male betta fish tank. These bubble nests are how male betta fish mark their territory. During this period you may notice that the stripes on the female betta switch directions. Once the bubble nest is intact, it is safe to put the female into the tank with the male betta. Read more about breeding betta fish
