So I hard-plumbed my tank last night with PVC, etc. This morning when I took a look at the tank I couldn't find any fish. So I openned my canister filters and found 1 in the first one and the other 3 in the second one! I did not put any strainers on the end of the intake tubes (obviously) so I guess they just swam in or were sucked in. I thought they were smart enough to know to swim away from currents? Anyway, they are all fine, somehow :dunno:. Just thought I would share!
