IS IT OK IF YOU PUT TOGETHER THE GOLIATH TIGER FISH AND THE VAMPIRE FISH IN A 6FT AQUARIUM?? JUST D TWO OF THEM...... ANY SUGGESTION...

I thought GOLIATH TIGER FISH got 6 ft. Look them up on you tube. On river monsters Jeremy wade caught a HUGE one.
They did not get big beacause there was no open space. I never thought they would need open space. But i put 2 together. Wild ones get huge!!!!the issue is that they are just not cut out for aquarium life. they grow enormous and unlike other popular giants like arapiama and datnoids they have activity levels that are similar to open water pelagic fish species such as tuna or salmonids, which constantly travel for miles. this makes them extremly claustrophobic and very capable of causing great damage to themselves and equipment in an enclosure setting. Nobody i've seen or heard of has managed to keep one larger then 24 inches.
