Dumbo Betta Pair Male & Female Mustard Gas 3cm (Betta splendens)A matched male and female Betta intended for experienced keepers or breeding projects. Bettas are territorial, so provide dense cover and be prepared to separate the pair if chasing or stress occurs. This variety is known for oversized pectoral fins ('dumbo' ears).
Origin: Captive-bred variety of the Siamese fighting fish, originally from Southeast Asia’s warm, shallow, slow-moving waters.
Feeding: Carnivorous—offer a high-protein betta pellet or micro-granule as a staple, supplemented with frozen/live foods like brine shrimp, daphnia, or bloodworm in small portions.
Tank Mates: Not recommended for permanent community housing as a pair; keep with care and be ready to separate. If housed with other fish, choose peaceful, non-nippy species and provide plenty of cover.
Aggression: High risk of chasing—only introduce together with supervision and the ability to separate immediately if needed.
Experience Level: Intermediate; best for keepers comfortable managing aggression and separating fish if required.
Water Parameters: Temperature 75-82°F (24-28°C), pH 6.5-7.5, hardness 3-12 dGH; gentle filtration and consistent heating are recommended.

Great coffee grinder!
Color: Silver
Amazing product. Easy to use and has different grades of grinding. Zero noise compared with an electric grinder and more control of the results (consistent). His size and weight make it portable and easy to carry.

Quite good as a start grinder
Color: Silver
Very good burr grinder with very functional adjustments. Holds the perfect amount in 1 go for my pour over setup. My only critique is that is has 3 unconnected hopper sections that are quite small and hard to hit. I have to be very careful to not spill and one can fill before the other 2 causing some difficulties closing the crank, but it just takes some self adjustments to get around. Overall I'm very pleased with it for the price.

Great Quality, Great Price.
Color: Black
I have used this for a few days now and it works great. It is very well made and has a large range of adjustability. It is quite small and easy to store. Definitely worth the money.

Nice Grinder at a Great Price
Color: Black
I bought this to use primarily as a travel grinder and found that it is great for every day use. It is not meant for large amounts but it is perfect for single, smaller brewing situations. The grind selection worked well and I "dialed" the proper ground size for my single sized pour over coffee maker.

Ceramic burr destroyed itself
Color: Silver
For the first two-plus months it worked fine -- the perfect grind and the perfect amount with a full barrel for my oversized coffee mug.
I've been using it once daily, more or less, on a medium grind setting of 25, and this morning the ceramic burr started to eat itself. This is not acceptable.

Circle Joy contacted me and offered to give a full refund on this purchase, which was gratefully accepted. This is outstanding customer service.
