They are very-low maintence,so bigger fish than a goldfish would be messier.
Yes they are. They produce a whole lot of waste. Be sure to change the water at least once a week and change the filter packets, too.
Goldfish are probably the messiest fish you can own. This is why just one goldfish on it's own needs a 20 gallon tank with good filtration
No They Are Not
No, a gold fish is clean
Dirty
No fish is really "dirty." I have heard of goldfish clouding up water faster, but I haven't raised goldfish in years. All I have are tropical fish.
You can use clean tap water for your goldfish, but not dirty or used water.
your goldfish might die and maybe eat to much or the water starting to get dirty
Clean water of course! Dirty water is full of pollution, and makes it harder for the fish to breath. Also, dirty water that contains high amounts of ammonia, nitrite, and/or nitrate can actually cause long term gill damage in goldfish.
Zero, goldfish need very clean cool water and are very dirty fish.
Tetras (unlike goldfish), do not excrete a lot, so in essence they would be "clean" fish.
Yes they can because I tried it on some goldfish and they ate it.Besides, they will eat almost anything!!Yes they can but if you have little ones do not give them big pieces. The bread will make their tank dirty very fast though.
Feed it a pinch of food in the morning and before you go to sleep. If the water starts to look dirty, you have to change the filter. That's about it.
Basically... the waters dirty Either you put too much food in and didnt scoop the leftovers out after a few minutes, or its just full of poo. Goldfish bowls are really bad for fish to live in, the smaller the worse. They get dirty really easy and when the water gets cloudy, the fish can get diseases and die
No, just one fancy goldfish requires at least 20 gallons alone along with proper filtration, aeration, and weekly maintenance that includes changing at least 50% of the water. Goldfish are quite dirty fish, and as such, the water can quickly become toxic causing ammonia burns, disease, and even death.
