This is a fairly broad question. In most cases, big fish eat little fish. But if the big fish Is relatively slow, or has a smallmouth, like for example a freshwater Angelfish, it can be housed with fast moving platies.
depends on the typeof fish you have ... if its a very aggressive fish such as an Oscar and you put a smaller fish in there with it chances are its gonna be ate
Yes you can.
go to the fish store and buy a fish net that hooks onto the tank then put the baby fish in the net no other fish will be able to get in
other cichlids or other aggressive fish
ok for a typical fish tank you will need a clean glass or plastic marbels or rocks. get a small plastic plant or other dec. to put in. you need dec. because fish like to hide. clean tank every 2 weeks or so. this answer is mainly for goldfish,betta & other small fresh water fish.
small ones
The turtles will eat the fish.
You put minnows or other fish well im not sure
Small, hardy, non aggressive fish are best. These include small tetras, rasboras, barbs and rainbows.
no you can not put a female and male fighting fish in the same tank because they will just kill each other
separate them If they are in the same tank, you can't; you need to put the ones that eat the smaller ones in a different tank.
No, it really isn't fair at all. Some fish can survive in a small tank like bettas but they won't be happy. Fish need approx. 1 gallon per inch of fish to thrive.
Bala sharks are non-aggressive. I have had several of them, and they have never tried to attack or harm the other fish in the tank.
