i love my amano and they take care of my algae. they lasted longer than my betta in the same tank that I am cycling. The shrimps molted twice already and the snail grew by 1 spiral of 1/4" in diameter. Today is day 25.
I heard ghost shrimps do not last too long as they are feeder shrimps.
I goto the Petco at Pasadena because Chung and his staff are very knowledgeable and they sound like aquarists because they know species, lighting, plants pretty well. Also, the bright color lifestock (fish, shrimp, snail) are easier to be seen in a tank and it's like a bull seeing a red flag for a betta.
I am thinking of starting a yellow, orange, blue velvet, or RCS shrimp-only NPT since aokashi has so much fun as shown in his photos....
