i had 8 healthy adult guppies, all under 1/2” (all are still quite young survivors from 1 shipment over one month ago, and one shipment over three months ago), and one big mystery snail. this tank was stable until…
…i added three tiny horned nerite snails i got in the mail yesterday, 1/4 diameter each, in the morning when they arrived. they did not look lively, but the accompanying instructions from aquatic arts said to give them 24 hours to recover from the shock of travel, etc, and to put an algae wafer nearby before declaring them doa. 9 hours later at guppy dinner time, no signs of life from the new snails, and a couple guppies seemed uninterested in dinner, but otherwise ok. then this morning, EVERYONE WAS DEAD.
except the mystery snail. and it’s all a mystery to me. a very sad one. what in poseidon’s blue marble happened?
