Out of all the freshwater species,
dwarf puffers (Carinotetraodon travancoricus) are probably one of the most common starter fish in the hobby. After all, they're the smallest puffer out of the bunch, which means they don't require a huge tank or an expensive food bill. In turn, this makes them
extremely easy to take care of, and they can actually be kept with their own kind - which is something that cannot be said of most puffers.However, if you're planning on keeping your dwarf puffers in a species tank, then it's a good idea to purchase all of your specimens at the same time and then later weed out the extra males. One of the most important things to remember about dwarf puffer fish is that they need to eat on a frequent basis - at least two times a day. Unlike other inactive species of freshwater puffer, you cannot go a couple days in between feedings. This means that you will have to take the time to learn your puffer's eating habits so that you don't accidentally overfeed them.
Since they eat so often, they also produce a large amount of waste and ammonia. This quickly pollutes their fish tank, which means that you will need to make sure that you are diligent about changing out the water your aquarium. If you don't, your dwarf puffers will quickly die from all the toxins that accumulate in their water.
