Choosing an adult or young fish is an important decision to make before you purchase your fish.

Young fish

The advantage to having a young fish is that young fish usually have a longer life span. However, when choosing an adult or a young fish, keep in mind that young fish are also more susceptible to disease and infection. Just like young children, young fish have weaker immune systems and have a harder time coping with harsh conditions.

If you decide on a young fish, that’s great. But, if you have other fish, you might need to keep your young fish in a separate tank until it gets bigger. Putting a small young fish in a tank full of larger fish may prompt the larger fish to bully the smaller fish. Remember that choosing an adult or young fish is really a decision that should be based on your needs as a pet owner.

Adult fish

When choosing an adult or young fish, think about your immediate needs. Most fish stores sell younger fish, but you can definitely find older fish too. The advantage to buying an older fish is, depending on the age, this fish may be ready to reproduce. Obviously if you want to get into fish breeding, this is an important feature.

If you’re choosing an adult or young fish and you go with an adult fish because you want it to mate, make sure that it’s still capable of reproducing. Ask the pet store clerk or the fish breeder if the fish is still capable of breeding. Chances are that it is.

Tips for any fish

Whether choosing an adult or young fish, there are a couple of things you should remember. Number one, always get your fish from a reputable vendor. Check out the fish store or the fish breeder well before you decide to buy your fish. Look for a knowledgeable staff, a clean environment and healthy looking fish. Don’t be afraid to check out a couple of vendors before you make your decision.

When choosing an adult or young fish, consider how much space you have. If you have a small tank, get smaller fish. A good rule of thumb for smaller fish is one fish for every gallon of water. Putting a young or adult fish in a crowded tank is not at all healthy for the fish.

After choosing an adult or young fish, you’re going to have to introduce the fish to its new environment. This can be a harrowing experience for a young fish and an adult fish. Choosing an adult or young fish is an important decision, but either will be a great addition to your aquarium!
