Do kribensis cichlids excavate?
I have a pair of kribs in my 55 gallon planted tank, and I recently went away on vacation for a week. When I came back, I was startled (and amused) to see that someone had been redecorating my tank. Piles of substrate had been pushed back from the front of the glass to form a little "mountain range" in the center of the tank.
I immediately suspected the kribs, but I've heard that they aren't diggers since they spawn in caves. Still, they seem like the likely culprits--am I right to assume this?
I should probably get them some more caves, the female's been vibrating at the male for a while now...and I don't need new landscaping, lol.
Other fish in the tank: 5 Congo tetras, 5 longfin serpae tetras, ~10 neon tetras, 4 volcano rasboras, 8 cory catfish, 1 whiptail catfish, 3 mollies, 1 lyretailed swordtail, 2 zebra danios. The danios and one of the mollies are "refugees" from my 20 gallon--I kicked'em out when I added other fish. They'll probably go to new homes soon.
Lol, yup, it's my kribs alright...just found the male busily excavating a new pit. He's starting to get a pink belly like the female, and they've both been going in and out of a little crevice lately...maybe I have baby kribs on the way!
