About three weeks are I placed 2 Siamese Algae Eaters to my tank. For three weeks they have not touched any algae and were just scavenging around the bottom. Today I introduced 3 ottos to the tank to take care of the algae because the SAE's weren't touching it. Well about two hours after watching the ottos eat algae the SAE's started to eat it and have been going at it non-stop since then. My guess is that since these guys are bred they are not familiar with algae (weird and crazy if you consider instinct and etiology). I think they were just emulating the Cory's in the tank and bottom feeding. Now since the otto's (captured instead of bred) showed them that algae is edible they learned a behavior. What does everyone else think? Am I being crazy? Would love hear people's thoughts and experiences with something like this.
