No, you can keep one or the other, but not both together
just your convict cichlids but, a jack would need a 55
If the tank is large enough. For rearing young Oscars a 50 gallon tank is about right for 5 fish.
Tiger Oscars really should only be kept with Tiger Oscars. if you can find a fish that can grow to be equally large and have the temperament to survive with an Oscar then by all means try to keep them together, but Oscars will eat anything.
yes they can
absolutely......NOT you are on drugs if you think so Oscars are very beautiful fish and deserve atleast a 30 gallon. if you would keep it in a 10 it will stop growing on the outside but on the inside they wont stop and eventually die from internal bleeding
No problem. Your filters are rated to clean up to or no more than 75 gallons of water. Less water is OK. 55 gallons is great size tank and your filters should keep it nice and clean. Your Oscars should be very happy. Don't forget to change the filters every couple of weeks. Have fun.
The Oscar fish naturally stay calm when they are in a pair.keeping more than two Oscars in the same fish tank can cause then to get aggressiveso keep two Oscars at the max in one tank.
Im not sure about the green terror but with the Oscar and maybe jack dempsey as long as your fish isn't full grown (10-14 inches) then it will probably be fine
Jack builds a thicket to keep away trespassers.
If you wish to keep other fish with Oscars you will need a very large tank. The smallest tank to successfully keep 2 Oscars in is 6 foot x 2 ft x 2 ft. Other large Cichlids from the Amazon area can be kept with them. The basic rules of fishkeeping always apply. They are :- 1 inch (2.5 cm) of fish needs at least 1 gallon (3.5 ltrs) of water. :- Every tank needs a permanently running cycled filter. Every tank needs at least 50% of its water replaced every week.
No. A 10 gallon tank is barely big enough to keep a single goldfish in.
The rule of thumb is to keep no more than 1" of fish per gallon.
