Wednesday evening, I added one Bolivian Ram to my aquarium. I've done some research on them, but I can't find anything about the experience I've had with this fish so far. Whenever I turn the light on, I find the Ram near or at the very top of the tank, in the corner. He's generally floating very still, looking like he's struggling. A few times, I actually thought he was dead. After a few minutes of floating, he swims off, and seems to be fine, and doesn't go back to the floating behavior until the next time I turn the lights on. This is the only fish in my tank who does this. Should I be worried, or is this typical? Maybe he needs more time to adjust to the lights than the others do? I'm also wondering if I can add just a few more fish this weekend or if I really need to wait the full week that's recommended before I do. My tank is stocked with 1 Bolivian Ram, 1 Krib, 1 Raphael Catfish, 10 Serpae Tetras and 7 Lemon Tetras. I'm planning to add 1 more Serpae and 2 more Lemons, and then top off my stock with a Blood Parrot. After finishing off the tetras, I'll wait at least a week before the Blood Parrot, but I'm hoping to add the Tetras sooner since they'll add so little to the bioload. My cycle was unchanged when I tested 24 hours + after adding the Ram.
