Is it ok to put food coloring in my oscar tank?

Question

Will it hurt my oscars to put food coloring in the tank to turn water blue.Oscars around 1 year old.

Answer 1

Although the idea never occurred to me when I was into fish, my first reaction is no.

I'd call up a fish shop (not Petsmart or Walmart) and ask them.

Why not use a colored light? But even then, I'd check with the fish shop - they might need natural light.

Answer 2

my daughter dumped some turquoise food coloring into my tank a few months back. i changed a LOT of water but it was STILL blue. but they are just fine. and the blue looked kind of cool. and a couple weeks ago i used food coloring to test the flow of an aquarium filter. no harm.

Answer 3

You shouldn't add anything to your fish tank besides fresh water and water conditioning for fish. That's it. Nothing more than that.

Answer 4

Why would you want to put food coloring into your tank? I don't think that would be a good idea, you could affect the breathing of your oscars, or possibly kill them. Not a good idea.  

Answer 5

ummm no.

it would probably kill them

Answer 6

No, it's just a one year-old fish! You could hurt it or you could make the breathing worst and it'll start dying!

Answer 7

No:  Food Colouring has chemicals in it that only large digestive systems can cope with.  And only very very very small amounts of it are used in food.  You would require a lot to do your tank so unless you would like a fish in heaven, i would without a doubt 100% say no.  Also, why do you want to?  Are you trying something out?

Hope this helps :-)

Answer 8

I wouldn't put food coloring in it. I bought some tabs to turn my pond blue, so maybe they make something like that for fish tanks. Why don't you search around online?

Answer 9
