Hi everyone, i have purchased and amano shrimp and it has been in my tank now for 2 days tommoro i am probably going to purchase 5 more but have concerns, the first night my shrimp was in my tank he was at the front eating and acting normal then today and yesterday he has completly vanished, i am not that worried about this because i do have a 140 litre tank and many hiding places such as ornaments and plants ect. my main concern is wether when i buy these new shrimp my fish might attackk them my fish include, (10) neon tetras, (10) rummy-nose tetras, (1) bristlenose plec, (2) catfish (not sure what they are called but they are about 3-4" long and about 1" wide, (1) Betta, (1) rainbow shark, (3) rainbow fish, and (6) fancie guppies can anyone help me to just make sure that these fish will generally be ok with the shrimp i have already told my LFS about the fish i have and they said it should be ok as long as you have a large tank, and many hiding places and feed your fish correctly, all of my ( semi-aggresive fish ) such as the rainbow shark or even the betta are small and not big enough to eat the shrimp as they are about 2" as it is i am just hoping that it will be safe and the shrimp currently in my tank will probably be ok. thankyou.
