Yes. It is just me, but I try (( not always successful )) to only purchase fish that can/will live out their lifespan in the tank that I have currently. In the past I bought fish for the tank that I planned on having... well, I still don't have that tank (( 6 years later )) and had to sell some fish that I had gown attacked too.
I can't tell you what to do, can just share what I have learned (( from my mistakes )) over the last 20 years or so.
