Finding dead animals in a heavily planted tank
Pretty straightforward question, really. Does anyone have any tips?
I have a fishy smell and the nasty film on top of my 50 Breeder, so I'm pretty sure something is rotting in there; actually found my first dead Amano shrimp (luckily) next to the glass in a corner last weekend and am pretty sure there are more since the film is back and the water is smelling foul less than 24 hours after a 70% change. Can't see the rear of the tank since it is against the wall, can't search while the tank lights are on due to the configuration of my DIY hood and have massive thickets of growth, R. rotifundolia, P. gayii, H. difformis and E. tenellus growing around a stump with plenty of (relatively) unaccessible open space underneath it. All my rummies and SAEs are accounted for, so the dead things would be Otos, Bushynose plecos or the aformentioned shrimp.
Help! Any and all suggestions are welcome!
