This is not possible as the required minerals essential for the growth of aquatic life would be absent.
You should not use distilled water in a fish tank as it is missing vital minerals. Distilled water is basically water collected from steam
Yes, you can and you should. Tap water should never be used in a turtle tank. Use Brita filtered water, or, if you can afford it, fill the tank with Poland Spring.
The turtles will eat the fish.
NO! Turtles are reptiles and should be kept in a vivarium never in an aquarium with fish. Reptiles and amphibians will foul the water and the fish will not survive.
No doubt they can live in a fish tank but it will certainly not do the fish any good. Turtles poo and piddle in the water and putrefy it making it deadly for fish to live in. They also bite chunks out of unwary fish. Please use your brains and don't try to mix Amphibians with fish. It can not and will not work in an enclosed aquarium.
Cloudy water is an indication of hard water and is therefore not adequate for fish, regardless of type. Try using distilled water or water fortified with specific minerals needed to allow your fish to survive.
No, not really, you need mostly water and a few rocks out of the water to bathe on, a big tank depending on how many turtles you keep, because they get BIGGER than you think they do! you also need a light and no other smaller fish with it.
I think it depends on the species. I have had two small red-eared sliders and two rather large gold-fish (they look like koi) in the same tank together. You must make sure that the fish have enough room to swim comfortably and that the water is not too deep for the turtles. It worked for me but the turtles refused to go in the water because they were afraid of the fish.
No, they will most likely eat your fish.
Some people do not believe it but the best water to use in your betta fish tank is tap water. Bottled and distilled water has been "purified" and does not have the minerals that your Betta fish needs. If your tap water is so bad that you do not even drink it, than use spring water.
Fairly long, at least a few weeks, due to the air breathing organ it has. regular water changes help: You can oxygenate the water by removing the fish and removing some of the distilled water then pour new water 4-9 inches above the tank..the higher the water the more oxygen (take into account how much water your tank hold, the less water the more splashing from a higher distance). Next, add some soft rocks that wont affect pH (ie quartz, slate), and some betta vitamins, all this will condition the water better for the fish and keep it healthy. Then you can put your fish back in the water, once the temperatures are the same.
You can make a Syrian hamster setup in a 10+ gallon fish tank. Make sure there is no water and that there is very soft bedding. You could also put various fish in your tank. The cool ones I think are the Angelfish, the Bettas, the X-ray Tetras, and the Neon Tetras. They need water and plants to swim around. You could put turtles in you fish tank. They need a very large tank though.
