First hello all I am new to this site and recently purchased a used 120 with a sump from a friend. I have a 75 right now with peaceful american cichlids 1 chocolate, 2 firemouths, and a blue acara. My question is since I bought the tank off my friend who is getting out of the hobby it comes with his stock. I have been researching on the inhabitants however and I am a little worried. The stock is 1 female con, a male and female salvini, and a male Red dragon Flowerhorn. He has had thee guys as tank mates for about 6 months. However after doing some research I am unsure if this stock will work long term. I have made caves for the sals to feel secure in. The female con follows the flowerhorn around like a lost puppy. Going forward what would you guys advise is this stock ok.
