Depends on how big it is.
The Violet Gobi is a brackish water fish (almost marine), and the Kissing Gourami is a tropical fresh water fish. They each need completely different water conditions and parameters. The conditions that would suit one, would kill the other.
fish need air because they won't be able to breath if they didn't have air, and fish need air badly because they spend most time in the water. fish need air as much as we do.
lower then normal tropical ranges 73-77F . and this are a brackish fish species prefering a salinity any were from 1.005 to 1.017. they need a fine sandy bottom for substrate with many ledges and caves(PVC tubing works) to hide in. they are detritus and algae eaters. so tiny food items and crushed algae wafers will feed them also don't keep them with aggressive eaters since they are virtually blind and must find food by smell. they can get to be 2 feet in length but 15-18" is more normal for captive fish so think of a large tank 75g+. also this fish does best in groups makes them a more aggressive feeder.
NO! Our eyes are not able to see the real colour of coral as fish can. We need to use an Ultra Violet light for the colors to reveal themselves.
no
The conflict is pretty much about violet getting surgery but she dosent need it
Goldfish don't need salt because they are Freshwater Fish!
Blue and red, violet has a slight blue tint so you will need to add more blue than red. It is best to add small amounts of paint to ensure that you do not add too much of a certain colour.
Too Much YesYou Still Need Protien In Your Body Though
A fish needs 20 litres in a bowl
No. There is not such thing as too much oxygen just too much carbon. It is good to have a lot of oxygen so the fish dont die because of no oxygen.
If you mean, how do act as Violet in the next film, then you need to get an agent who will audition you.
