Do goldfish mind algae in their tank?
« on: May 01, 2008, 11:04:27 AM »

I have a fish tank with 2 goldfish in it. The fish are around 7 years old - going on 8 in march. I have some algae in the tank and was wondering if goldfish like the algae.  It is a 10 gallon fish tank that has a filter attached to it.   Because when i see in ponds and stuff they seem  like to eat the algae. But that algae was green, the algae in my tank ls more of a brownish color. Can anyone help!


Basically what i am asking is this, Do goldffish like the algae or does it bother them and harm their health.

Fish are not bothered by  algae at all. Many of  them even like to eat it.

If you do not  like it , however, you can use an algae scrubbing brush and clean it off. It will  also help if your tank is not in direct sunlight, which can stimulate algae growth. An algae eating fish often is not necessary.

It is great too see that your goldfish have lived for such a long time, but a bigger tank is really much better for goldfish. The bigger the tank, the longer your fish will live - and goldfish can sometimes live for more than  20 years! Smiley

Hi All,

Something to share with goldfish lovers. I had 8 Oranda for 2 months on a newly setup tank. The water is clear on the first 2 weeks and algae start on the 3rd week. On the 4th week the algae is so thick, I can hardly see the fish if is away from the glass. I normally remove 2/3 of the water for each change. Each change can last for 2 days before it gets murky again. I believe this is because of the nutrien from the fish waste has come to a level where is suitable for the algae to bloom. What I did is use a small suspended basket (to prevent goldfish from consuming the vege) and place water spinich (Ipomoea aquatica) inside. With the day light floracent tube, the plant grew and water becomes crystal clear in 4 days!!! No magic trick and I am amaze. Explanation behind could be these plant consume the same nutrien as algae and basically compete for it. Nutrien level goes down, water clears and gold fish happy and healthy. Note that because of its 'hungry' nature, other plants in the aquarium can be affected by it presence. Therefore, I do not introduce other plants into the aquarium.
