I bought a pair of bolivian rams 11 days ago. I am pretty certain they are a M/F pair. They are in a 60 gallon peaceful community tank with perfect water parameters (0 ammonia/0 nitrites/0 nitrates) and weekly 25% water changes. When they first arrived they colored up nicely and went exploring. Soon after a good exploration they found a spot they liked under some driftwood and rarely came out. They are also showing a darker coloration but still maintaining their bright colors (pink/yellow). Most concerning is that I have yet to observe them eating anything (lots of observation). I feed sinking cichlid pellets (hikari), sinking shrimp pellets, algae wafers, tropical fish flake, and frozen bloodworms (obviously not all at once). Even when the food lands right next to them, they take no interest. They appear skinny, but I think at least one of them is looking a bit less skinny today. In the last few days they will leave their "spot" and swim around the tank a little for a few hours in the middle of the day. If they truly weren't eating at all they'd be dead, right? They came from a big box store and I have until Thursday to return/exchange them if I wish. Are they just still stressed and shy from being in a new tank? Are they bad stock? Is this degree of shyness normal?
