Who hasn't pondered how long their aquarium fish will live? With no hair to go gray, it's hard to tell if that fish you brought home is a youngster or an old-timer. For that matter, even if you did know their true age, you probably have no idea what their normal lifespan should be. Although there isn't a definitive listing of lifespans for every species of fish, they've been studied long enough for us to know a bit about their natural lifespan. Interestingly enough, there is quite a range in average fish lifespan from one species to the next. For instance, Bettas
live only a few years, while Goldfish
can live for decades.
However, just like people, individual fish will vary from the average. Even though the average human lifespan isn't 90, most of us know someone who is still going strong at that age. And just like people, keep in mind that fish are more likely to live longer if they are given a good diet and healthy living conditions. Wondering how long will your fish live? This fish lifespan reference
will give you a general idea of how long your fish may live.

Recently a friend chatted with me about a fish he was interested in. He didn't know the name of the fish, but once he began describing it, it didn't take long for me to figure out he was talking about a Blood Parrot
. Few fish are as distinctive in appearance as this man made cross-species. This species is also one of the more controversial fish in the aquarium trade, due to the fact that some believe it is wrong to create them. However, plenty of people adore them and feel it is perfectly natural to make new and interesting cross-species. Regardless of what side of the fence you are on, they are well established in the aquarium trade and not likely to go away. Join the debate by sharing your thoughts

Unless you live under a rock, you probably know that eating junk food is not ideal your health. But what about the food our aquarium fish eat? We all spend a lot of time concerning ourselves with the tank and other environmental factors, but often we forget that the food we offer our fish is just as important. Do you know if you are providing your fish with the nutrients they need to lead long healthy lives, or are you giving them the equivalent of junk food? Don't worry, Nutrition 101
has all the information you need about fish food nutrition.

Cory catfish are among the most beloved of the bottom dwelling fish. What's not to love? Many are small, most are lively, and all are peaceful. Cory species are all schooling fish, and do best if kept in groups. Although they stick close to their own species, don't be surprised if you see different species of Cory cats swimming together in one large school. There is safety, and fun, in numbers.
Another trait all Corys share is ability to take in oxygen from the air. Although they can only take limited amount of oxygen this way, it still allows them to survive in low oxygen waters. They also share another trait - their armor. This protective armor is composed of overlapping boney plates that Corys are graced with, instead of traditional fish scales. It serves as a great deterrent to predators. Numerous Cory species exist, in fact there are almost two hundred species already officially described, and many others that remain unnamed. Here are a few of the more popular Cory species
found in the aquarium trade.
