No oscar will eat it
I have an Oscar Cichlid in the same tank as mine and I also used to have it with guppy's.
that probably wouldn't be a good idea.. the Oscar will probably eat it.
An Oscar needs at least 55 gallons, and common plecos can grow to a foot long - you must make sure you have enough filtration for this
NO! Turtles are reptiles and should be kept in a vivarium never in an aquarium with fish. Reptiles and amphibians will foul the water and the fish will not survive.
A small oscar can live in a 10 gallon for a short period of time. However, oscars are fast growers and can reach lengths larger than a foot so a larger tank would be required soon.
How long does it take for a oscar to get used to a new tank
Yes can very well. Fish will only grow to the size of the tank so that means the Oscar will probably only get about 6 inches tops. And i would eventually upgrade to a 30 gal tank withing the next 6 months.
A Redtail and an Oscar are two different types of fish
maybe
no
They should be OK together if they are about the same size and you have a large tank (Over 50gals) set up. If you have a pair of Oscars and they decide to breed you will have to remove all other fish.
No They Are Likely To Attack Each Other.
