I think that the shark would eat the goldfish probably.
I suggest don't try it.
It is not recommended. Tropical fish come form a warm climate while goldfish are cold water fish.
You should not have goldfish and platies in the same tank ever.
yes, but it may kill the goldfish
yes! yes they will. Red tailed sharks are very aggressive and territorial not to mention that they will go for the goldfish's long fines.
no
Rule of thumb is to not mix tropical fish and goldfish.
No, Neon Tetras and Goldfish do not belong in the same tank. Goldfish prefer cold water, while Tetras are more of a tropical fish.
Sharks will eat anything!
Of course!
Yes, but your tank size needs to support it. If you mean that a regular goldfish is a long single-tail goldfish, then you need at least a 40 gallon tank just for the 2 fish due to the size potential of the common goldfish. If you mean a regular goldfish as in a round bodied fantail, or perhaps a ryukin, then you need at least a 30 gallon tank for the 2 fish.
It's a possibility, but a goldfish and a platy should never be in the same tank as they are not compatible, and their needs are different
Goldfish release growth-inhibiting hormones into the water they live in: the more goldfish in a smaller space, the less likely they are to grow. For instance, if I have a common goldfish in a 5 gallon tank, it will grow to about the same size if I had 6 of the same fish in a 30 gallon tank. But leave that fish alone in a 30 gallon tank, and it will grow larger. This is why pond goldfish grow bigger. But goldfish won't grow at all in seawater; they aren't saltwater fish.
because sharks are big then rays and perch and goldfish..
