Chick-In-Of-TheSea Posted February 23 Share Posted February 23 (edited) Posting for a friend that is not a member of the forum. She had 4 guppies and 1 BNP in a 10g w/ 2 mysteries. A mystery snail had pitting of the shell and she added crushed coral, less than the recommended amount, 1 week ago. No other changes were made. Last night all 4 fish and the BNP died. The snails are active. Parameters before: pH 7.4 Temp 78 kH 1 gH 0 amm - 0 no2 - 0 no3 - 10 Parameters after: pH 7.4 Temp 78 kH 8 gH 7 amm - 0 no2 - 0 no3 - 10 After the deaths she was thinking about the fish, thought "maybe" she saw a little bit of stress in the guppies, nothing major, throughout the week. Could the cc have caused the mass dieoff suddenly? No water changes were done since cc was added. Edited February 23 by Chick-In-Of-TheSea Link to comment Share on other sites More sharing options...
