By a regular basis I mean will they buy my fish regularly or on a weekly or on a monthly time period-kind of like a monthly subscription. Also, what do I need to do to sell my fish to them? Do I call or just walk in with my fish?

They will buy them anytime. I would recommend calling first, just to be safe because you don’t want to put your fish through all that extra stress, in case they say no. I’m curious though, what kind of fish are you wanting to sell to them? Maybe I’ll buy it from you 🙂 I have 2 tanks. 1 is 65 gal and 1 is 125 gal.

I would take a few fishes to the store with me and make my sales pitch.

I'm selling fancy guppies. There three weeks old just getting color and about half an inch. I have about 30-40
