Maybe, it depends on what kind of rocks..... some may be too rough for your fish and hard to clean. Try to get smoothish rocks so they are easy to clean.
Steps to cleaning the rocks
1. soak rocks in HOT water for about 5 min.
2. apply a pea size dot of soap in the warm water
3. add some more warm water to make it bubble
4. scrub the rocks thoroughly for about 20 min.
5. rinse the rocks off very well with warm/hot water until the soap is gone
the hotter the water, the better put fish in another bowl with room temperature water... clean out the fish tank out more ROOM TEMPERATURE water in the tank then put the rocks ( that WERE cleaned) in the bottom of the tank arrange them how you would like then carefully put the fish in there tank.
I am not aware of magnets having any effect on goldfish. Maybe a large electro magnet created by passing windings around a tank then applying current through the winding could have an effect but a simple magnet placed on or into a fish tank should have no effect on the fish whatsoever.
Yes, because sedimentary rocks can change into metamorphic and metamorphic can change into igneous rocks.
Sedimentary, metamorphic, and igneous.
Any type of rock can become metamorphic.
Any rock mostly igneous rocks but in their molten state, because the inner core has a too high temperature.
Yes! But seriosly, the rocks wont make any difference!
Regardless of the type or size of goldfish the minimum acceptable size of an aquarium for a goldfish is 30 gallons. Buy a tank that is at least 30 gallons if you plan to have goldfish. You can comfortably fit 3 goldfish in a tank this size but no goldfish in a tank any smaller. Goldfish are essentially pond fish and need lots of space to swim; they will not thrive in a small aquarium.
Absolutely not. Goldfish belong with goldfish, and not with a bichir in any way.
No, goldfish are freshwater fish. Any goldfish you buy in the store are tank bred and not wild caught.
If the goldfish is a fancy variety, it can live alone in a 20 gallon tank. Goldfish do not belong in tanks any smaller than this as they grow very large
almost any other type of fish just make sure their bigger than the gold fishes mouth or the goldfish will eat it
No, if you do that than the parent goldfish (and any other goldfish around) will eat all the eggs and any possible fry.
godfish can be any color-not just gold. yes u can put them together if they r the same breed (goldfish)
No goldfish would prefer to have a lower temperature than any type of tropical fish, however some goldfish can withstand higher temperature if they are slowly acclimated to it! But in the long run goldfish would be happy with other goldfish and tropical fish with tropical fish... there is a reason you don't see the goldfish with the tropical fish in a good aquatic store.
No. The only thing that can go into a 1g tank is a betta, and that's barely okay. PLEASE don't put any number of goldfish in a 1g
This will depend on the type of lighting you use, whether there is any sunlight shining on their tank (or pond), and the type of foods. If your fish are primarily in a location that does not get direct sunlight, and your tank lighting is low, fish tend to be less colourful regardless of what you feed them.
Any time you plan to put rocks of any type in your tank, make sure that you clean them very well until the water runs clear; if you do not clean them properly, you could introduce illness to your tank.
