Ok I am a newbie at aquariums and I have 3 comets and 1 common that are overwintering inside in a 10 gal tank. I know that is small but it is all I could get my hands on, because my pond freezes solid. Its not very deep. Well I havn't had any problems yet and today I notice the biggest one is chasing the others away from the new anacharis plant I put in a couple days ago. Could someone tell me what might be going on. I was thinking that it is to small so thats why its chasing the others but I don't know. Could someone please give me som ideas.
