It depends on what kind of fish, and the size of the aquarium.
they cant do to lack of oxygen beiing used up.
Algae can grow back in as soon as 5 hrs.
If it hasn't got a filter you are limited to the type of fish that will live happily in your aquarium. In any case, use prime in the water to dechlorinate it and neutralise nitrate and nitrite. Without a fliter, you wont have your fish for long and will need to do daily water changes.
Coyfish cannot be kept in an aquarium, but it's not because of the answer below. It's because they are so badass they will break through your measly glass and run free as they should be, you fool! And if for some reason he cannot manage to break the glass, a passerby will because they will notice how amazingly badass he is and want to set him free. End of Story. ---- Hi. koi fish can not be kept in a aquarium as they grow as long as 36 inches!!! only suitable for a 1000 gallon pond.
Puffer Fish lives from 4-8 years
Millimeters may be appropriate, or perhaps centimeters. If a fish is 63 mm long, then it would be 6.3 cm long. U have to take the fish out of the aquarium
you can as long as you have a filter and a fish tank
Pipefish will live for 5 to 10 years with proper care in an aquarium. It is vital that they are provided the right water temperature, food, and tank-mates.
can you tell me the name of a small goldenfish that walks on its fins and is only 2inche long at this time
There are fish from several genera called Frog fish (Angler fish). They require specific marine living conditions in order to survive. In a fresh water aquarium they would be dead almost immediately.
they can't
The "Moonfish" is more commonly known as a "Platty". Their lifespan is usually around 3 or 4 years in a well run aquarium.
Defiantly not goldfish. They produce a ton of waste and need a massive aquarium to live a long and happy life . Maybe try a betta because they do not need a big aquarium . REMEMBER all fish need a home that is clean and is maintained properly . RESEARCH FIRST !! And enjoy your new fish . X
Yes, if they are cold water fish and they are in there for a long time. Tropical fish could stand the water a bit hotter. But not too hot. Though i would'nt try it.
Koi are pond fish and grow to over 24 inches or so when adult. It is unlikely they will breed for you in a small aquarium. (It is also unlikely they will live long in a small (under 75 gallons) aquarium)
Saltwater fish are very hard to keep, and it absolutely takes an established aquarium, and not just a tropical aquarium with salt. You have to have special "live" substrate, preferably "live" rock, and all levels of ammonia, nitrite, nitrate, and salinity have to be monitored very closely. A saltwater tank is for advance aquarium keepers, and it consumes a lot of time and takes a lot of work. I am sorry for your loss, but there is a lot of information available on the web on how to keep fish. Try getting him a betta or something. A saltwater fish won't ever survive long without a saltwater tank
