Most tropical freshwater catfish found in home aquariums are Plecostimus fish, abridged as "Plecos" though often referred to as "algae eaters." These tank-like bottom feeders start out at only a few inches long but can grow to well over 2 feet and feed off of algae and other particles in your aquarium. Plecos come in several different forms, including the bushy bristlenose pleco and the stunning (but very small) zebra pleco, known for its bright white and black stripes.
Fish that are called 'eels' have a long snake-like body. Most are without a separate dorsal and pelvic fin, rather their fins appear merge together with the tail fin to form a continuous fin fringe. Most also have small gill opens, often just a single gill slit at the throat. Eels vary in size but the average size of most species is from between 12 - 36 inches (30 - 90 cm) in length. In their native regions many of these fish are considered a good tasting food. There is only one order of fish classified as true freshwater eels, this is the Anuilliformes Order of eels.

If you were to try to pick one up by hand you’d probably get spiked.

The best way to catch one is in a plastic container. These freshwater aquarium catfish are among the most docile and unique in the entire hobby.Be careful when introducing the flat-nosed and antenna catfish into a freshwater aquarium. Their large mouths can easily capture smaller fish accidentally as they forage for food at night.

Do not pair them with angel fish; the sharp barbels of the flat-nosed catfish can injure or kill angelfish.Even though there are several varieties of long whiskered catfish only one is really suitable for freshwater aquarium use, the Pictus Catfish. The Redtail and Tiger Shovelnose Catfish grow to sizes approaching 4 feet making them unsuitable for all but the largest aquariums and ponds and tank mates are hard to come by for these large aggressive fish.
