There are some species of fish that are very prone to Ich infections and some of the loaches (in particular Botias) are well known for it. Ich is one of those bugs that have to be totally destroyed otherwise they will continue to come back. I would advise you to buy a good Ich cure from a pet shop and follow the directions exactly.
Catfish and sharks
No, sharks and catfish are different types of fish. Sharks are cartilaginous fish with sharp teeth and a streamlined body design, while catfish are bony fish with distinctive barbels on their faces and often have a flattened body shape. Additionally, sharks are typically found in saltwater environments, while catfish are usually found in freshwater habitats.
Like a catfish
Catfish, eels, sharks.
Some examples of fish without scales include catfish, eels, and sharks.
No it is not. Salmon are a species of fish just like sharks, trout, tuna, clownfish and catfish are.
Some catfish are commercially fatmed, but there are other "commercial fish" that are farmed.
Humans but in the ocean, catfish with the barbs removed can be used as live bait in the open seas. There is no 'common' enemy of catfish. They are just as vulnerable as minnows when they are small.
These are saw toothed scales. One of the fish that has this kind of scale is the American Bass.
They just know......
Salmon, bass, catfish, trout, sea bass, swordfish, marlin, tuna, sand sharks, hammerhead sharks (!), and MORE!
Basa fish, just like all other forms of catfish, is not kosher.
