shells

[krib]

hello the krib here i was wondering if any one can tell me if it is alright if i put a rather large shell that i have been given in to my fresh water tropical fish tank or if it will affect the fish cheers

wash it well (maybe even pour boiling water on it - use the kettle ) and it should be fine.

Depends on the shell. If it came from the ocean (salt water) don't use it in a freshwater tank. Something about the calcium, I think. Don't remember.

If it came from a freshwater lake or something similar, it should be ok after boiling.
