One of my Labeotropheus Trewavasae (malawi cichlid) is acting really strange. it's just hanging out at the top of the tank in the corner. at first i thought it was dead, but after i went at it with the net, it swam away. but after a few minutes, it went right back to where it was!
Here's what's going on with the tank. I hadn't been paying attn to the temprature in the tank lately, even though the room temprature has been rising with the spring season. well, apparently my heater was set too high. Now i just noticed this, so i turned it lower so the water can cool down. the temp of the tank was nearing 90 degrees. during winter it was usually anywhere from 80-85 degrees.
I'm thinking he may be staying in that position because he's trying to cool down or something.
also, i read this page: http://www.cichlid-forum.com/articles/l_trewavasae.php
so maybe my air mixture isn't good?One of the most interesting things about the genus Labeotropheus is their characteristic curved-over, upper lip. This is an adaptation that helps them to scrape algae off of rocks. Many of the Labeotropheus live at the mouths of rivers, where the current is very strong. Their curved lip allows them to scrape the algae from a more horizontal angle. They have thus adapted to this habitat, whereas other fish who have to approach the rocks from a vertical position are unable to battle the current while in this position. Trewavasae have also adapted themselves to this oxygen-rich habitat. They require water with a high saturation of O2. In fact, I have noticed that when my tnaks are overcrowded, the trewavasae are always the first to linger at the top, gasping for air.
edit: also note that he doesn't like to stay vertical, (s)he has been turning his body to an angle,
