As far as I can gather, they simply out-grow anything that is likely to eat them.
it hides in trees
they como them selves
The only catfish I would try to keep with large cichlids is something that grows large and can defend itself like a Plecostomus. Don't expect any catfish to eat rubbish or poo. They won't.
yes they did discover the blue catfish
Yes. The blue catfish is found in many states, including Michigan.
Unless it is a localized indigenous name, (common in the American South) they are known (properly) as "Blue Catfish", a specific species of catfish.
Mainly by flight, but could be dangerous with that long, powerful, stabbing beak.
A Neon Blue Guppy doesn't really defend its self it usually hides.
It eats fish
Blue catfish are the largest American catfish.Found in a variety of habitats,they can grow over 100 pounds!They eat mostly fish,but will take a variety of baits,anything with a smell.I saw a man catching them on chunks of soap!Blue cats are powerful fish,and fight great when hooked.They spawn in spring,and the young resemble tadpoles.
A flower may have thorns such as a rose does enabling it to passively defend itself .
Blue catfish can get almost 8 feet long but other species in china can get even longer.
