So I am going to dedicate my 120g tank to a single Male Midas or Male Red Devil. I have 3 Clown Loaches in the tank that I would like to keep, they are between 3-4inches. I plan on giving them ample hiding spots and plan on getting the Midas or Devil young so they can grow together. My question is I want to ensure myself a bull male (biggest, thickest, and best kok potential) so are there any tricks to spotting this or how many should I get to grow them out and pick the best one. Also, I know I can't put any other fish in but could you recommend any dithers(pref not silver dollars)? Also since the Clowns are already 4inches and the devil will take a year to get big, they should be fine together right? Thanks for the help!
