I am setting up a 600 gallon planted tank (7 x 3 x 4 ft) that will have a large sandy foreground area with wood mulch and botanicals. I also have in my fish room a group of 9 Dicrossus warzeli and another group of 10 Biotoecus (I can't remember if I got them as opercularis or dicentrarchus - how do I tell?). I'm thinking of adding both groups of dwarf cichlids into my planted tank to add some activity amongst the botanical covered sand and am wondering if both types would coexist together. They seem more chill in groups than other dwarf cichlids like apistogramma and ivanacara so I'm hoping that this would work out. There would also be cories in the tank.
