Lack of oxygen mate! Id be quick and put some oxygen in the tank or bowl, If a tank, the best idea would be to get urself a air pump (about $15-$25AUD), an air flow tap/adjuster (which is a little piece of plasic about 3-4cms long), get urself some air hose 2-3mtrs and an airstone for about $1.50-$3. The cheapest thing to do which is effetive but not the best way would be to give ur tank a 75% water change and get urself a few LIVE plants from ur aquarium, it will probably cost u between $5-%20 depending. Some plants to look out for are ELODIA- its really good with oxygenating, WISTERIA and banana lillies. You could even put an OXY BLOCK in there too, That would help heaps and would probably set u back $3-$4 extra. If you have a bowl, do a %75 water change right away and add live plants and oxy block. If u have a reasonably large bowl u can put a pump in aswell if u like. Cheers champ :oD catch!
U buy tropical fish and get a background and then that is how u can do that
no tropical fish need warm water
Your fish is gasping for air because it needs air to live. if you don't already have one, I recommend getting a aerator. This allows air to be in the tank with them still being under water. The fish fuzz, I don't know about.
No. Not in the traditional definition of the tropical tank. A tropical tank is a freshwater aquarium. Regal Tangs are saltwater fish and go in a saltwater tank (marine aquarium).
why not
Probably the fish. I would not put a crab in a tank with tropical fish unless they were a LOT bigger than it was, and it was not going to grow any larger.
Use a tropical fish tank, preferably new. That way you know that it should not leak. Try to avoid using a tank that was used for something other than tropical fish. I prefer glass tanks over acrylic because they are less likely to mark or look dirty and they are easier to keep clean. Most aquarists will tell you to start off with a small tank and as you enjoy it more and more, you can opt a larger tank. When I started into tropical fish and as I bought larger tanks I used the smaller tank for breeding. Tropical fish tanks and supplies are available in most pet stores that sell tropical fish.
You can tell if your fish tank has enough oxygen for your fish by observing their behavior. If they are swimming near the surface gasping for air, it may indicate low oxygen levels. Additionally, you can use a water test kit to measure oxygen levels in the tank.
if you have a tropical fish or a filtered tank than yes you do need a light
Only if it has a heater in the tank other wise the tropical fish will die. They are warm blooded instead of cold blooded.
Usually there is a heater that warms the tank on purpose.
nothing!
