This is a sad day indeed. Have been buying fish from Jeff for 20 years or so, and a couple times since Kevin took over as well. Without TUIC and also CoA, our options to find these species nowadays are pretty slim. I've had good experiences with a few other online fish dealers (wet spot for one ), but it's not quite the same as having a dedicated cichlid specialist vendor.
Kevin is on this site- I know lots of people are grateful for the service TUIC provided for many years!
Jeff is still around the internet as well, I follow him on IG and he mostly posts wildlife photography, seems to be living happily in retirement.
All the best to the TUIC team and thanks again for everything!
