these blue rocks are definitely that bright blue they are very pretty the only downfall I saw was it's not a very big package I have a 5 gallon fish tank and I had to order two packages to fit in my tank so if you have a bigger tank of 20 gallon or bigger you're probably going to need 10 boxes of these rocks because there's a hardly any in it I mean there's might be two cups of rocks or cup and a half of rocks and that's it and then they come in some weird packaging that like opens up because mine were opened up in the box and spilled everywhere I had to pick them all out and put them back in their package and it opened up and shipping but other than that they're really pretty it's just not for many of them
