hey guys. i got a dragon fish...don't know why i did cause it sucks... but i was recently cleaning my tank and couldn't find it...so i just figured that it was eaten by my red devil...about two days later i was feeding my fish and there he was just swimming around like normal...my question is this...when i clean my tank i remove all the plants and wood and large rocks so i can use a gravel vac to clean it out with...he wasn't hiding in the small rocks because i sucked them out. i now realize that he was just hiding in my wood log that i take out when i clean my tank...it was out of the tank for at least 30 min. how is it still alive???
