Hi, could anyone please help me identify whats wrong? Over the last two weeks i've purchased 3 commom plecs, (seperately, as 1 as died i have replaced it) all have only lasted a day? They have appeared to be fine & ok in the tank. I purchased another 1 yesterday seemed fine in the tank got up this morning & again the plec is dead, all three that i have purchased have all been dead the following morning? Any help please? Checked water stats all is fine, plenty hiding places, tank been established roughly 6 months, the tank mates are: 2 female 1 male black mollies, 2 female 1 male white mollies, 2 female 1 male swordtail, 1 female 1 male platy & dozen neons. I really cannot find anything that is or what im doing wrong, any help or suggestons would be very much appreciated. The aquatic place where i have purchased the plecs have replaced each 1 yet that has died (havn't yet returned yesterdays plec that i purchsed) Don't really want to purchase another till i can try & solve the situation?
