I got 2 baby RES a couple weeks ago. I have an internal filter and a little basking are I made out of a kitchenware item and some rocks. Bridge is a little wooden/rattan board, really light. I've seen Luffy and Ninja basking and swimming around and being all active before. I also added a bubbler rod of some sort. The internal filter's top part is just 1.5 inches below the water level, so they love to sleep there at night. I also have some stones at the bottom of my tank, not gravel, big ones, that I'm pretty sure even an adult RES wouldn't be able to swallow. I also have a cuttlebone I put behind the filter's suction cups so it won't float around because it just floats to where the ledge is and would block their basking access. I also have 2 small conch shells of some sort.
For the past 2 days Luffy has been acting a little lazy, not like Ninja, who I always see swimming around the tank. Luffy still basks but when I'm in the room he just hides in their sleeping spot above the filter. Is something wrong with him? He doesn't look like he's sick, eyes are okay, shell and skin looks fine. And he eats just fine when I transfer them to a different container for feeding. It's just that when they're in the tank and I just sit and stare at them, most of the time he's chilling on top of the filter while Ninja swims around and basks.
Need help and opinions. Thanks so much...
Oh by the way, forgot to mention. They're still really small, like 1-2 inches SCL.
