Is it suitable if fish also live in the tank?

Yea it's just slow release calcium

Does it make the water cloudy/dirty at all?

Do not buy this. It is so bad for your turtle. Buy Cuttle Bone instead it leaves no cloud and is 100% healthy. Please don't buy this it's so toxic Nd can make your turtle seriously ill

Is this suitable for tortoises ?

This isn't meant for tortoises and is meant for slow release in water for aquatic turtles/terrapins. My terrapin bit it to pieces quickly and probably consumed some too without harm. I would think a tortoise, especially a large one, would quickly destroy it too, and perhaps consume too much in one go. Zoo Med do a larger tortoise block which I have found excellent for my tortoises. It is bigger, more substantial, and therefore takes the tortoise much longer to consume the calcium and wear down its beak in the process. My Horsfield tortoise actually mounts the block so you could say its environment enrichment at the same time!!
