I knew someone who had a very large goldfish in a 5 gallon tank she cleaned daily while removing him to a bucket. No bubbler or filtration either! She had him 12 years that I knew of and refused offers of bigger tanks... what else can you do? I lost touch with her so I don't know how old this fish lived or if he still lives! :-)
How often do you clean/change water
I have a small 3.5 gallon fish tank with a small filtration system in my classroom with one goldfish in it. There are small rocks at the bottom of the aquarium. I have noticed that over the last couple of weeks (we have had the fish for almost a month now) the water has turned cloudy. I need to know what we can do to make the water sparkling again and to make sure “Fred” is well taken care of. Please advise on what I need to do to make the aquarium shine again and how do I go about cleaning the aquarium. Do I remove the fish from the tank and wash out with distilled water? I need advice. The last thing I want is to come in and have to tell my kids that Fred is dead!
I have a 5 gallon tank with one male betta
However, I’m not certain how active danios are. I would go to the fish store and watch the ones you are interested in. If they do a lot of swimming straight ahead, a 5 gallon tank may be too cramped even if you get the small ones. When I picked out my tetras, I watched them and they usually darted 1 or 2 inches and then changed direction. From that I figured that they didn’t need a really wide tank. You can also find small tanks that are extra long, but not very deep or tall. For more active fish, that might be better. Remember, the smaller the tank, the more work you may have to do to keep it clean!
