Guppies are slowly dying
Over the weekend I purchased 3 guppies - Not sure what kind they are, or if it matters but they are pretty small... one yellow/green leopard print, one yellow and orange flame like one, and another an orangish pink. All had pretty small tails.
This is a pretty new tank and probably was not cycled properly, but I did let it run for 3 weeks while adding fish food occasionally. It is planted and has ecocomplete substrate. I have noticed a "film" on the surface and I'm wondering if that is normal. I tested it before getting the fish and everything was normal, and after getting the fish everything was still normal. EXCEPT my pH which is at about 8.2. I did read that guppies can have a pH near 7.8 so am I pushing the limit and could this be killing them?
I woke up the day after getting them to the pink one dead. Currently the leopard one is dying, he can flit around a little bit but then nose dives into the substrate. I did notice he is missing([?] not sure if he had one) his upper fin and whats left is almost hair like projections leaving me to think they were fighting, although I had seen no aggression at all. The last fish seems to be completely fine but that's what I thought about the leopard one after the first fish died. I am feeding them topfin tropical feed as the petstore told me, currently the alive fish eats a little but spits some out. I don't think the food is the issue at all though. At the pet store I did notice one fish in the tank that had the same symptoms as the leopard one now. Could this not be my fault?
update while typing: The leopard one is trying to eat, the filter is blowing him around a bit, should I turn it off? At first I wondered if it was too strong for them, but they seemed to be obsessed with the current and swimming up it, instead of going to the area of the tank that was not affected. This is a Fluval Spec V by the way. The other fish is definitely interested in what's going on and is swimming around the leopard one.
