Ok, thanks. I didn't buy a tang yet, just planning it out ahead. I imagine I'll get the smallest fish I can find at lfs. I'd like to put it through TTM before quarantine. Rubbermaid tub is a good alternative- don't know why that didn't cross my mind lol. Thanks again.
Ah yeah, definitely get the smallest, but for it to live in a bucket for a couple weeks might stress it out too much.
There are a couple posts with small tanks, even 5 gallon buckets, on Humblefish's thread on this topic (they may or may not have been used for tangs). But yeah, go with the tubs instead...
