Lost two fish over the last 2 days

Not sure what's happening. Water parameters seem fine but I'm losing fish. My algea eater died yesterday and then today a platy died. We added 3 platys and the algea eater on Friday to our 20 gallon tank. The 3 tetras we have had for a while are seemingly fine. Not sure if the dwarf frog is attacking the fish. I don't know what else to do to see why the fish are dying.

what are the parameters? are they new additions? any tank work recently? check temps, PH, etc.

I need to check ph but Nitrites amonia and nitrates are all 0. I haven't bothered the tank in a week. I'm due today for a water change.
