i have a 75 gallon tank with a red devil, green terror, jack dempsey, texas, and a plecotomus. the first three fish get along fairly well, but the green terror constantly messes with the texas and it is always in caves or up behind one of the three filters. i have another tank that is up and running with nothing in it but plants, and i was planning on moving the texas to it. the texas is about five inches now,and the other tank is only 30 gallons. if i put the texas in it solo will it be alright, and do i have room to add anything like a loach and/or pleco?? any help would be great. thanx
