Hello, I am new to aquariums and bought a biorb a few weeks ago for my
daughter, we bought 3 platys to start the aquarium and have had them about 3
weeks. Last night however I could only see two fish, getting home from work
today I am definate there are only 2 fish. The other must have died but I
cannot find it. Should I take the fish out of the tank and empty it to find
the dead one?or will this cause them too much stress?
Any suggestions appreciated. I don't know how I coulld loose a fish in such
a small tank!
