Only if it has a heater in the tank other wise the tropical fish will die. They are warm blooded instead of cold blooded.
I am guessing that you mean a Plecostomus. The answer is NO. Each of the species needs totally different conditions. Goldfish are cold water fish and suffer when the temperature goes over 75F. Plecostomus are tropical fish and suffer when the temperature goes below 75F. They will both survive for a while in one anothers parameters but eventually they will die from living in the wrong conditions.
# Marine-The marine fish have to have saltwater these fish would live in the reefs. # Coldwater-Goldfish fantails (I have these) the normal goldfish. These are other type of coldwater fish- clam,plec and mountain minnows. # Tropical-These fish come in a range of colours and types including pink glass fish,plec,tetres,parrot fish,silver dollars,guppy and shrimps there is many more. # Pond Fish-Simlar to gold fish but live outside in a pond it is a good idea to cover your pond with chicken wire so no birds can eat your fish. I think that it would be a good idea if I tell you the guppys (tropical fish) breed easily.The males have a fancy tail where as the females have normal tails. if your fish do breed it would be a good idea to get a net that goes in your fish tank so no other fish eat your babies.Also the swordtail breed easily the males have a sword like tail and the females have a normal tail. I thought you might need to know this just in case it does happen.
Gold, Gold star, goldfish, gold dust, gold medal.
It has been reported that goldfish will loose colour if kept in low light conditions so I guess if you are silly enough to want to not see your fish and keep them (it) in the dark to find out if it goes white that is your right.
Yes, but it will die! Someone swallowed my beloved pet goldfish.
you can put an algae eater in with any tropical fish, I even have a goldfish in with my tropical fish now for almost 8 years. Pet store say no but i beg to differ. 8 yrs going strong, gold fish, algae eater, angel fish, silver dollars. Some fish are more dominate over others. I have learned no matter what they are if they are put in the tank, all as new fish as the same time, they all get along. After one dies, then as time goes on a new one has to earn its peck so to speak, so new ones get picked on. I have an algae eater and a cat fish. all is good.
It is best to not use salt in a goldfish aquarium unless as a treatment for parasites in the tank of a sick fish. The salt damages nitrobacter bacteria that help keep water quality good and causes the fish to produce a thicker slime coat which stresses out the fish thus making them more susceptible to disease.
Alright, so first it depends on the fish you want to get. For tropical fish, the general rule is 1 gallon to each inch of fish, as for goldfish, you need 2 gallons for each inch of fish (This, i know, goes against the sterotypes that goldfish can live in miniature bowls, but this type of living environment greatly decreases their lifespan) and at this point I am not sure of the rules for Saltwater aquariums. As for the filters, they usually say the GPH (Gallons Per Hour) and the size aquarium (In gallons) that it should be used in. It also depends on whether you are going to breed fish, sponge fliters are great temporary filters for a breeding tank. I hope all this was helpful!!
As a general rule of thumb tropical water is consistantly above 65F and goes as warm as required by the species of fish.
What happens is the food rots in the tank. This rotting/decay creates gas (Ammonia) and that will poison the fish and burn its gills. This results first in sick fish and then death.
They should be able to if it goes soggy in the water because they could eat it very easily.
I can answer your question without you having to search and search. The good rule of thumb for freshwater is one inch of fish for every one gallon, but goldfish and saltwater are different. Goldfish need 3 gallons of water to every inch of fish, same goes for saltwater.
