Hi everyone, I am new here so if I have missed anything please do let me know. I have a 50 gallon tank set up, it has been set up for some months now. I do 20% water changes every 7 days and my water readings all appear perfectly normal The tank is stocked with: 1 Clown Loach 2 Pleco 8 Female Guppies 8 Female Platies 1 Male Platy 6 Cardinal Tetra The tank did have 3 male guppies which have now all died and a male Platy which has also died. The bit that concerns me is that they have not died together. they have died about 3-4 days apart. The tank is planted and sits at around 26 Celsius. Does anybody have any ideas if I am doing anything wrong? my only thoughts at the minute is possible bullying between the species which I am missing or something I am not testing for. Any help would be greatly appreciated. I have only recently started with my aquarium and have had this "hobby" for about 6-8 months in total.
