would it be possible to house a chain dogfish, two or three flashlight fish and a few comb jellies in a three hundred gallon tank? if so how cold would it have to be?
the temperature ranges are too different. the flashlight fish are 72-78 F
the chain dogfish 55-68 F
the comb jellies 39-87 F (p.s. jellyfish need a round tank cuz if they get stuck in corners they get torn up)
you could possibly do flashlight fish and comb jellies or
comb jellies and chain dogfish.
up to you. hope this helped.
Chain dogs are good buy themselves. Talk to Josh (Turbo) if you need some. They do well with some fish as long as you keep them fed. There are a few cold water schooling species that would complement the sharks well.
Flashlights and Jellies should be done by themselves. I've only seen them do well in a speices type tank.
