(by several different people, disregard use of I) Don't feed goldfish to Oscars. The stuff left behind after eating live food is pretty nasty. I only fed live food a couple of times per week b/c of the mess and for cost reasons. Also, feeding Oscars live food is a good way to make them sick. If you …

The chlorine level in the pool should be maintained at 1-3 ppm throughout the year, and shocked about once a week with either chlorine or a non-chlorine shock. During the winter, the chlorine level will tend to stay about the same unless the pool is heated, but the chlorine level must be maintained,…

You can put any fish that will fit into a bowl inside of one, but keeping is another matter. Much as it's potentially possible to keep a dog alive for a while inside of a closet, don't expect the health of the dog in the closet or the fish in the bowl to remain anywhere near optimal. Besides, fish h…

If you want to keep fish I would strongly recommend buying a fish tank with a filter. I have noticed with only one fish they get lonely and just sit there as good as dead all day (of course this depends on what species of fish you keep!). They seem to be happier in groups if they're shoaling fish, s…

Mostly they love algae. This is why they move up and down the sides of your tank-they are eating algae. Even if the glass looks clean, there is microscopic algae there. However, if you have a brand-new tank that has no algae at all, you need to purchase algae tablets at the pet store so the snails w…

No. After spawning the male will chase the female away from the nest and then defend the nest. In the wild, the female would be able to move well away from the area, but in a tank she should be removed. Have a look here for further information: bettaparadise.co.uk.

Not in a gallon bowl. Bettas are best in 5 gallons plus. Bumblebee Gobies in 10 gallons plus. If the tank was larger though, it would depend on the size and temperament of the Bumblebee Gobies.

No. In pet stores the fish do not have lights on 24/7 as you said anyway, Fish do not have eyelids so they cannot shut their eyes to sleep, this means they need pure light to see and pure darkness to sleep. I keep the light on for something like 6-9 hours per day and leave the light of at night so…

No!

No, bettas, like all living animals, need the regular cycle of night and day. Bettas also usually relax/sleep during the night because they feel like they're in a cave and more secure.

That answer is correct. The packages typically lead you to believe that you need to feed your betta 2-4 times a day.

Take it out immediately. Uneaten fish food will decompose rapidly and foul the water. As the decomposes, Ammonia and Nitrite are produced in the aquarium water.

No, they cannot. When water evaporates, all minerals, chemicals and solids are left behind. Fish eggs cannot "rise" or "float" with the water. Many ponds that have dried up and refilled by man or rain can get tadpoles in them which are mistaken as fish by some.
