im getting a 135 gallon comes with everything but water plants and fish. i plan to get fill for it but dont know what kind it will be a half planted half caves and tunnels i have done tunnels in the past and my cichlids absolutely loved it i used the hampster tubing and burried it in the fill. great trick i plan to have a mound of fill on one side about 14inches high im not worried about price but it is a concern lol also i do not like spending an arm and a leg on fish i was just going to go with either african or south american cichlids oh and if someone can give me a pointer on identifying males and females in african cichlids that would be great also i would love to start breeding them i have a 10 gal planted with a male betta and a fan tail goldy and a 29 with 9 tiger barbs(1 green 1 albino) and some pleccos and a blood red jewel chichlid currently. please cover me with your ideas/knowledge
