Hi I am new to fish keeping and aquariums. I have decided to buy betta fish and along side with it some Amano shrimp and Otocynclus as cleanup crew. But want to know best website to buy these from. I know fishes are fragile creatures and I want to buy from those who keep fishes in good condition. I saw some websites online like freshwater aquatica but I don’t know how good they are or if they’re even legit. Some recommend me a good place to buy fish from.

Edit: fish tank I will build myself and size will be 2x1x1.5 feet cube
