Hello all,
I recently swapped to a new tank for my fish with extra space (10gal to a 35gal). My fish were very active the first day I put them in swimming and checking out the environment. I only have 4 fish two Cory’s and 2 glofish. When I changed tanks I made sure to add sand to accommodate the Cory fish and they seem to like it. But today 1 Cory has been laying in the sand all day and I can see it’s still moving a little bit but not nearly as much as the other Cory and 2 other fish. I tested the water with strips and it came back at good levels and it’s cycled but I did put rocks at the bottom to level the sand and stuff underneath. I cleaned the rocks thoroughly but they are just regular rocks (not marketed for aquariums) so I’m unsure if they are safe to keep in. I put boiling water to clean them as well. I have a heater at 77-78 in the tank. The tank is also cloudy compared to the last tank and I’m not sure if it’s because of the rocks or something else. Any and all help is welcomed I want to make sure my fish are alive and well (got them from petsmart btw).
