Freshwater Fish Aquarium Beginners Should Avoid

This guide will help you avoid fish that will provide young aquarists problems and stress in the aquarium hobby.

1. Freshwater Sharks - Bala sharks, Iridescent sharks, Columbian sharks, etc.
"Freshwater sharks" are common targets by young aquarists because, well, they're sharks! These aren't true sharks and are a no-no in any beginner's fish list. They're massive waste producers, grow very large(some up to four feet) and will soon end up being given away to other aquarium owners. There are exceptions though, like the Red-Tailed Shark and the Rainbow Shark, which are easy enough for a beginner to manage. These large sharks aren't impossible to keep, but it's best to leave them to more experienced aquarists.

2. Goldfish
Goldfish are often sought by beginners as their "first fish," but they'll soon know that they're not the best choice. They are often put in small tanks and bowls, which will soon lead them to their demise. Goldfish cannot survive in small tanks because of their large oxygen requirements and heavy waste production. A good alternative for goldfish is the Siamese Fighting Fish or Betta, which are more suited to live in small tanks(though they still appreciate a bigger tank). But if you have a large enough tank(20 gallons), there's no reason you shouldn't keep these beauties.

3. Large Tetras - Pacus, Pirhannas, Congos, etc.
These fish are very interesting and even tasty to eat, but are certainly not for an aquarium beginner. They are often sold in stores as juveniles, but they will eventually grow very large even for the average aquarists' tank. They also need to be housed in schools of at least six, which further extends the problem of space. They're omnivorous, but they should have lots of live foods, particularly the infamous Pirhanna(which may be illegal to keep in some countries). Even if you have a very large tank, their care requirements would be way too much for a beginner, so it's best to leave them at the pet store for now.

4. Large/Predatory Catfishes - Common Plecos, Red Tails, Chinese Algae Eaters
Common Plecos are often the first choice of beginners as their tank's algae eater, but these fish have a problem in terms of size. They can grow up to 20 inches, and so will require a tank of at least 55 gallon tank. If you can provide this tank size then you may be able to keep these fish. Chinese Algae Eaters are also often sold to beginners as an algae eater, or are sometimes mistaken as a different fish(Siamese Algae Eater or Otocinclus Catfish, which are excellent algae eaters). They'll eat algae as juveniles but as they grow their diet will switch to the meat of their tank mates, so be very careful when choosing among these fish. The Red Tail Catfish is another massive beauty that grows way too large in even the largest of aquariums(1000 gallon should do). You will find these little Red Tails very often in the tank, but always keep in mind that they are meant to be kept in a pond, not an aquarium. If you're looking for a neat little catfish for your tank, the Corydoras Catfish are a good choice because of their small size, interesting behavior and participation in your tank's clean up crew.

5. Arowanas
Did you see an elegant arowana in your local hospital's aquarium the other day? Planning to get one for yourself? Well, you might think otherwise. Even for advanced aquarists, arowanas can be difficult keep, mainly because of their massive size(around 100cm). They are also powerful jumpers(they're called "river monkeys" in the wild) and will need lots of live food. The same is true for other large fishes like Snakeheads, Bichirs and Clown Knifefishes. Truly exotic and beautiful, but should only be left with people that can afford to care for these creatures.

6. Clown Loach
Ah yes, the ever popular Clown Loach. They're well known for their comical behavior and striking coloration, but for young aquarists they're not a good choice. They are extremely sensitive to declines in water quality and are among the first fish to die in the aquarium. They also grow pretty large(12 inches), require to be in small groups and are very prone to catching Ich. Clown Loaches are among the most demanding fish, but once you have had enough experience in the hobby, these fish are worth the try.

7. Freshwater Rays
Exotic, beautiful, dangerous - Freshwater rays are an excellent example of fish in the "deadly beauties" category. They are monstrous waste producers and are picky eaters(will eat only live foods). Getting pierced by the poisonous barb at the end of their tails is truly excruciating and fatal. They will need a very large tank of at least 350 gallons. These reasons are more than enough why beginners should stay away from these magnificent but deadly creatures.

These are some of the fish that beginners should stay away from in the aquarium hobby. Most of them are beautiful and exotic, but don't let yourself be fooled by these deceptive creatures. As the saying goes, "There are many fish in the sea"(in our case, rivers and lakes) - rainbow fish, gouramis, livebearers, small tetras - these are just a few species of fish that are both beautiful and undermanding. Remember, aquarium keeping isn't meant to be a burdensome task. By selecting your aquarium specimens carefully, you will be able to avoid much problems and enjoy this beautiful hobby to the fullest.
