Thank you everyone for all the nice compliments. And yes - I have always had some very high OCD tendencies in EVERYTHING in my life. Nothing medically diagnosed, but counting stairs when I take them, everything has it's 'place' and if it's out of place I literally can not walk away from it without fixing it, yadda yadda lol.
The self control on stocking comes from 30 years of extensive fish keeping experience, and knowing what's best for my fish. I have a deep love and respect for all animals of every kind, and my fish are absolutely one of my top priorities (goes my dogs, my cats, my fish, my husband...he's aware lol). I like big, highly aggressive cichlids and I know that comes the responsibility of large tanks with solo fish because I want them to be happy and healthy.
