Tropical lagoon is far and away the cheapest with the best looking fish to me.
Ihave bought 3 dozen fish over the years with not 1 problem.
Stay away from hot for fish....they are the worst.
Cte very bad selection poor health.
Go fish has healthy fish been in the business forever.
There is a petco in gb that i get some cheap fish that i have good luck with
they also get some cheap uchins.
My 2 cents.
