Heys guys, well i am new to the discus hobby but have kept and bred many cichlids before. I now only have 1 tank but i used to have 40 . I have just set up a tank it is a 3 ft std tank with 2 corner filters and gravel would this be ok for some discus my ph is between 6.3 to 6.9 . How many discus can i keep in this tank and is there any other things i should know. I am scared that when i put the fish in they will die cause of how many bad things i have heard with discus getting diseases and all sorts of stuff so any info will really help me out. I live in sydney and i am thinking of going to the discus club for a look any opinions? Sorry about how long this question is
