A 1 gallon tank could have one betta fish, but you will need to be diligent about changing the water on a regular basis. The smallest tank that should be used, even for a betta, is a 2.5 gallon tank as it at least gives the fish swimming room.
you can put a betta in a 5 gallon tank
normal rule for fish in a tank is: For every 1 inch of fish there is 1 gallon of water
In that 150 gallon fish tank try to put fish and maintain it
You can put it on a table if you choose. NEVER put a tank on the floor.
No
Yes.
Danios or glofish would be a good fish to put in the tank. They are schooling fish which means you would need at least three and I wouldn't put more than 5 in a ten gallon tank.
Remove the sick fish..... the fish that has the ich should be put in a hospital tank then treated for ich, corals do not get ich, only the fish, so a ten gallon tank with a aerator would be ideal for a hospital tank....
The fish are not bad together. But way to many fish for a ten gallon tank. You put one fish for every gallon. They will probly do fine but you will have to clean more.
NONE! ZERO! NADA! Never put chlorine in your fish tank. You want to remove chlorine from your tap water before using it in your tank.
precisely 2.2
That is small better stick with a goldfish.
