I purchase two small one from a online store in oregon... their fan were all bang up which increase their risk of death....out of the two...none survive ..
One would live 3 weeks and then die.....a month later the other one pass away. My tank is planted and well mature with strong spray bar.
I ask my local fish store to order some for me... somehow they were able too (surprise..walkk in there and saw them week later)
I decide not to buy them at first cause they just got them in not long enough...i wait for maybe 2-3 weeks?... this unsure that they are able to live in the local tap water and that the weak one (with fan damage) have pass on and that the strong one with good fan did indeed make it...this also goes for bamboo shrimp too.
After that, I finally bought a large one....till today (2-3 months) later it has been hiding under my driftwood, fanning and haven't come out at all. ( i find bamboo shrimp to be less shy, they don't give a dam..alway out in the open)
They are very very shy and once they find their favor spot, they ain't coming out!! DO NOT move any decor or plants once they do that, you will cause them to be stress.
Till tis day, i await the day he will come out and explore.
As for feeding, I bought some spirullna pellet for the fish and it spread around the tank and the shrimp fan for it...keeping it alive.
