If by "comet fish" you mean a comet goldfish, you should not put anything in with it unless you get a much larger tank. A comet goldfish can grow six inches or longer, and will need a larger tank. Any tankmates should be cold water fish, like the goldfish. Snails will also get along well with the fish, but might get eaten. If it is a marine comet fish, it will grow up to seven inches, and will also need a larger tank.
I breed guppies in my 10 gal tank. They like temp between 70-80 and eat tropical fish food.
shark lion fish whales and dolphins and alot other kind
Mice live on land, fish live in water. On in not the normal prey of the other.
Some are. Like any other kind of egg, fish eggs vary in size and color according to their species. They're kind of clearish red, but it probably depends on the fish
it depends how big the tank is. since this type of fish stays relatively small, use the one inch of fish per gallon of water rule. mollies are a grouping fish and should be kept with 4-6 or more of their own kind. you can keep them with platies, guppies, swordtails, endlers livebearers.... many freshwater peacefull fish will 'play nicely' with them.
cat / fish...tada! its a kind of fish
One gallon is really just too small for any type of fish, but 2.5 gallons or more would be great for a betta fish.
You don't! What you do is get a 55 gallon tank because angelfish won't be happy in a 10 gallon tank, and then you take the betta out of the tank (it will fight with your other fish) and just get more mollies and put lots of hiding places in the tank so the babies will live.
A short period comet.

That is small better stick with a goldfish.
A comet one stupid.
The basic rule for keeping any kind of fish is. 1 inch of fish needs a minimum of 1 gallon of water.
Which kind? Glass or acrylic?
It depends on what kind of fish you are keeping; Goldfish and other 'cold water' fish prefer to be around 65-70F. Freshwater tropicals around 80F Marine tropicals around 78F
You could put the following: 3x Neon Tetra or... 1x Betta
Depends on the kind and size of the fish. You should also take in to consideration how large they will get at adulthood. A good rule of thumb to go by is 1 gallon of water for every 1 inch of fish. So for example: 3 2" fish should be in at least 6 gallons of water. To be safe I would put them in a 10 gallon aquarium.
