dear all
i recently (about 2 weeks ago) changed all the gravel in my tank
because it was totally infested with malaysian trumpet snails (i think
there were more snails than gravel!). i think the tank then cycled
after that because it was cloudy for a few days. since then i have
lost four fish, firstly a cory, then a harlequin, then another cory
and this morning an otocinclus! what can i do to stop my fish
dying??!! is it related to the water change? my molly fry (x8) are
all fine and growing well. help!
