Yep, an airpad. Poor buggers need it. I know cichlids need to be overcrowded, but in a 30L?? The photo shows the kid which says it's an Aqua One 350, which turns out to 30 L/ 7-8 US gallons.
Sorry to spread the sadness, my mind just boggled a bit. @Wills , do you know what kind of fish these are?
No afraid not, know next to nothing about africans. A lot of cheap africans (as I assume these would be) are often highly hybridised. You do see shocking things all the time, I once saw in person a fancy goldfish in a Fluval Edge, the small one, and it had grown too big to get out through the hole in the top!
