Piranha's 101 guide to maintaining healthy piranha in the home aquarium

O.k.! Now that you've learned the nature of piranhas, let's discuss how to keep piranha healthy in the home.First of all, you shouldn't consider keeping piranhas in anything smaller than a 29 gallon aquarium. Some piranhas can grow to be quite large, but most importantly, piranhas require a larger aquarium to maintain their health. Piranhas are very "tough" fish, buy if not properly cared for, they won't get "comfortable" in the home aquarium. "Uncomfortable" piranhas will soon succumb to disease or other piranhas in the aquarium.



Piranhas such as serrasalmus spilopleura can be incredibly ferocious if properly cared for, but if proper care isn't given, it could turn into a timid fish that always hides and never eats.

Secondly, you should have a good filtering system. Piranhas make quite a mess when eating, and this mess of fish parts ends up rotting on the bottom of the aquarium if not taken care of properly. The best filtering system you can get is the expensive wet/dry filter that is used by most pet stores. The next best filter would be a diatomic filter (canister) such as the “Magnum 350". These filters are both expensive, and if the money isn't right, then you should consider a filtering system such as the "Whisper" or " "Emperor" series of filters.

Fish give off waste products just like you and me, and this leads to a buildup of ammonia in the water. To help counter this you need some sort of biological filtering system. The expensive wet/dry filter has this built in. Otherwise, you should consider an underground filter or "biowheel" filter. This will help combat the ammonia problem, but 25% of the water should be exchanged in your aquarium once a week regardless.(It's not necessary if you check your water regularly, but it's a good rule of thumb).

Next, you should densely plant your aquarium, both for hiding places, and to keep competing piranhas from killing each other. Live plants also help to combat the ammonia problem. Try to keep an area in the front of the aquarium open for swimming.

Here is a good example of how to plant an aquarium for a single piranha. If more piranhas were to be added to this tank, many more plants would be required in order to provide shelter from the "aggressive" piranhas in the bunch.

When caring for diseases that your piranhas might get, I've found the best all-around medicine to be Formalin:

Another thing to consider for your piranha aquarium is the low lighting condition required by piranhas. They are "nervous" fish and require a dimmer light than most fish. You can place thin cloth over the light opening, or get a light blocking case to cover your florescent tube. Either one will work fine.
Also, to keep your piranhas from hiding all of the time, you should consider covering the exposed sides of the aquarium with some sort.

Also, to keep your piranhas from hiding all of the time, you should consider covering the exposed sides of the aquarium with some sort of cloth or """backround"' leaving only the front of the aquarium exposed for viewing. This will help your piranhas feel more secure, and will in turn make them "happier."

It is actually formaldehyde in a diluted form. If the directions are followed properly, it cleans up just about any disease that your fish may get.When adding fresh water to your aquarium, it is always a GOOD IDEA to de-chlorinate the water and condition it.


Now comes the fun part:selecting your piranha. Their are several species of piranha available to the home aquarist (depending on your location) The most common piranha is the serrasalmus nattereri or red-bellied piranha. These are hardy fish and are probably the easiest to maintain.

On the other hand, if you are an experienced piranha owner, and would like to own one of  the most deadly and “meanest” aquarium piranha, then I suggest that you get a black piranha, or even a white.  The are both “mean” in the home aquarium and will attack anything put in the tank.  Including things much larger than themselves (such as other piranha and your hand).  These piranha need to be raised with care, for they are truly dangerous in many ways.  Personally, I have owned almost every species of piranha available to the pet industry.  I have found S. Niger to be the most challenging (and rewarding)  because these fish are devilishly mean, extremely pretty, are they are probably the boldest of all home piranha species once they reach maturity in a stable in environment.
