No. The copper pennies will slowly release copper into the water, which will kill most small fish. Avoid having any metal in your aquarium.
yeah just clean it well before with some diluted bleach and let it dry out. lizards have bacteria on their skin that can harm the fish
All Glass Silicone Aquarium Seal can be found at most pet shop's.It is best to buy the product for fish aquarium's .Other sealer's could harm your fish.
No.
no if you keep the lights on all the time it will create algae faster in the aquarium
No. Charcoal bits will harm your betta fish. But you can use deactivated charcoal bits
Fortunately phosphates do not directly harm your fish, even at high levels. However, the algae blooms that result from elevated phosphates can ultimately cause problems for the aquarium inhabitants. For instance, green water can deplete the oxygen, which in turn can harm the fish.
Once you have snails infesting your fish tank you will find it very difficult to get rid of them. They seem to live no matter how hard you try to kill them.
Aquarium salt can be used as a medication for certain illnesses of tropical fish including guppies, and used at the correct concentrations for a specified time, it could help a guppy get better from its illness. If on the other hand, if salt is just added to the water for no specific reason then at low concentrations it will do very little harm. At higher concentrations it could well kill guppies.
Copper sulphate is used in the control of algae. Whether dacaying pennies is enough to control the growth on an unknown volume of pond or birdbath is uncertain. Why don't you get two birdbaths, put pennies in one and nothing in the other and see if it works? But, be careful with your results. The birds may like the one with the shiny coins better and poop in it more, because it is more popular and cause it to grow more phytoplankton. note: Only pennies made before 1982 are 95% copper. Newer ones are 97.5% zinc and 2.5% copper. Use a piece of copper pipe instead. Copper works as a preventative algecide mostly when the copper is in a dissolved state and floating freely in the water. This is why copper sulfate works well because it dissolves whereas pennies will not (unless the water is acidic). I would expect the pennies would leave a relatively cleaner spot where they lie. I would just buy a small bucket of 3" chlorine tablets and let one slowly dissolve at a time, won't kill wildlife because of the relatively small concentration of chlorine released over time, unless you place them in a spot where water RUSHES by the tablet.
YES. Ammonia is the mostdetrimentalwaste that you could find in your tank. It can really harm your fish and species. It is all apart of the nitrogen cycle so the bestrecommendationfor high ammonia is to balance out this cycle by doing a water change or adding plants to the aquarium to produce oxygen to aid in the nitrogen cycle.
fish harm rivers and we do by dumping our rubbish in them
Actually the copper will start to corrode. and may cause infection.
