Just got back into the hobby about 6 months ago. I too suffer from MTS, currently have 4 tanks with fish, and 1 that is in process.
125 gal - Green Terror, Blue Acara, Nerite snails, Giant Danios
120 gal - Oscar, Jack Dempsey
75 gal - Texas Cichlid
40 gal - Convict Cichlid
90 Wavefront from 2004 I just purchased for my gf to have her own community tank
I was very into the hobby when I started where most the tanks originated, but as fish went away, I let tanks be empty for some years due to college and life. My 120 housed my original Oscar for about 9 years before I had to put her down. That was about a year ago now she died. Still have my Texas and a old lady Convict from those days that live alone, in my Geriatric ward.
