Good luck!!
Listen, i am asking in mass, not density, i dont care how dense the item is it will make no difference i just want to know if you know how many punds of decor will displace 2.2 gallons, and as for the other question, either answer it and have a good time or dont even bother
Sorry wrong answer to 2nd answerer, no matter how large something is doesnt effect the mass unless the item is dense, a small 1 pound rock is exactly the same as a extra large 1 pound rock, just the larger one will take up more space, trust me, i got 98% on my mass/density/volume and such test so dont mess
 
ok im not answering but how do you know people aren't looking it up in another tab, and 4. is difficult because you don't say, i want one that can live in a tank or what, it could be blue gill (thats not the right answer since alot of fish are bigger than them,) would salmon count since they are freshwater then they go to saltwater?
 
"how many pounds of gravel or rocks or decorations will displace 2.2g?"

bad question...a denser object vs a less dense object with the same volume will weigh more pounds, but will displace the same amount of water.


" a small 1 pound rock is exactly the same as a extra large 1 pound rock, just the larger one will take up more space, trust me, i got 98% on my mass/density/volume and such test so dont mess"

that is exactly my point. if a 1 pound rock can take up different amounts of volume, how do you know how much water each pound of rock will displace?
and 98 on such a simple test is nothing...d=m/v, big deal
