I'm pretty sure they do, not quite sure sorry :)

Ability to spend the require time and energy caring for the fish

Cost of treating the fish if health issues develop i.e disease

Cost of maintaining the living environment i.e. heating filtration, cleaning etc

Cost of food , especially if specific food types are required

Cost of fish to start the environment off

cost of additional "hospital - quarantine" facilities for new fish or those with illness

Glow fish are Zebra Danios that have had a jellyfish gene added to them to make them glow. They will eat Brine Shrimp avidly.

a gill cover is used to cover the gill on the fish

Yes algae fish are cold blooded all fish are cold blooded.

Yes, someone who catches fish for a living would be happy to see a myriad of fish. This is because a myriad is a large group.

Assuming you are not allergic to either, yes. If you are asking from the perspective of Orthodox Judaism, check out the web link -- not all fish qualify. By the way, Jewish law prohibits eating fish with meat. I would assume it's therefore considered dairy.

Fish have fins which help them to swim. Different fins have different purposes like moving forward, turning and keeping upright position. the paired fins help them to move forward. The unpaired fins help them to maintain balance and the tail help them to change the direction.

The Pilgrims "planted" (buried) the fish next to the corn as fertilizer. Or to put it another way - burying the fish acted as compost.

Tuna sells for the most money in the Japanese sushi market.

Fish can not be amphibians. The big difference is that amphibians breath by gills or spiracles when they are young and develop lungs as they grow and undergo metamorphosis, while fish can only breath via gills.

Not exactly a "unicorn fish" but there is a creature known as a narwhal. This is a species of whale, not a fish. The males bear a tusk that resembles the fabled horn of a unicorn.

Even though sharks are among very few fish which have eyelids, they do not blink. Most species of sharks have special nictitating membranes which go over their eyes to protect them when they are hunting or under attack.

Yes and no. typically plankton applies to microorganisms that are not fish. They are small microscopic animals. But more properly, plankton means drifter or floater. Anything that floats can be called a plankton. For example, the Porteguese Man of War is a plankton, while a copepod and diatom is also an aexample of plankton. Some plant are considered to be plankton and some algae are forms of phytoplankton.

Yes, because as long as they are still alive and 'kicking', they can pin your with their barbs (Catfish) or you could poke your hand on their dorsal fins (bass, rock bass), and they can bite down if their jaw is free, but with a thumb in their mouths, they can't produce enough force upward to bite you.

(Try it with yourself and push down as hard as you can on your bottom row of teeth, is it easy to bite your fingers?)

Blob fish survive by laying on the bottom of the ocean floor and eat anything that floats by!

when female guppies are just about to give birth to their young ones they start breathing very fast and try to hide from other fishes and even male guppies as they'll attack it.one more sign is the gravid spot near the anus enlarges and gets dark and just before the birth the eyes of the fry can be seen through the transparent body of the guppy

The Wolf Fish has 400 teeth which is 4 times the amount as the piranha fish.
