Is color of Light important in a tank??

the light fixture is it incandecent(like the traditional globe light bulb'hot') or is it a flourescent bulb? fish need light cyles but any bulb will do for your particular set up(no plants)

For the fish, the lighting cycle is more important than the type. Cool white lights with low red spectrum are better, as they won't encourage algae (though algae will still gorw if there are nutrients available).

On the flip side--the stocking you have is not good. Fancy goldfish and comets don't mix well, as the comets can outcompete the fancies for food and prefer cooler water and all will outgrow the tank quickly--it may be big enough to support one, but nothing else. Second, Angels and goldies (of any kind) won't work in the long run. Angels need much warmer water than the goldies will tolerate, and prefer a meatier diet than the goldies will do best on.

Sorry, but the situation is pretty bleak for keeping the current stock. If you return the goldies, and can heat the tank to be stable around 78, then there will be a number of options. Or, return the angels and the comets--the 2 fancies will be okay for a year in the 25, as long as you are diligent about water changes, though in the long run, you're going to need at least a 55 for them. The comets will hit 24+ inches rapidly--they won't be an option.

the compact high output flourecents that screw into incandecents. those are about the best out their. walmart have those in 10 watts wilth full spectrum. the bluish color probably meants its a plant/aquarium bulb wich is highr\er in the blue(infrared spectrum). depending what side of the spectrum the light source is higher in it will give that color off. eg. the sun gives off every color of light but is higher in the red /yellow side wich is hotter than the blue/violet side of the spectrum. the full spectrum lights give more light (less invisible light like ultaviolet) and have a better CRI color rendering index 100 is as good as it gets meaning replication natural sunlight. hope i was helpful

the other coment on the goldfish mixed with angelfish... i agree there are complications there your angel will probably get the majority of the food. i have had both angels and goldfish. i would put the 10 gal back into operation and once re established put the angels back in their by him/herself(s)

Fancies: moor, redcap, veil tail--all the goldfish other than the comets, which are stream lined with typical length fins. Comets are often sold as 'feeder' goldfish. They are all the same species, but the fancy variations make the fish less able to compete for food against their agile cousins. Koi are also similar, but can be distinguished from comets by the presence of barbels on their chin.

Thanks OrionGirl.

Kindly let me know which ones are the comets you are talking about. I was pretty sure that Redcap and Black moor are exotic variants of goldfish and belong to the same family.

I had posted this about six weeks back when i had got the 10G and nobody pointed this out.

I have a heater on and maintain a regular temp.

Yes, I did point it out. I also gave you information on the other goldfish you had and pointed out that the tank was too small and a lot of other information on goldfish requirements.

I just went back and reread all the posts you made:
