Looking for advice on what action to take if any.

Over the last 2 weeks I have had 4 fish die. First a Platy looked like a pinecone which ive read is dropsy which is a symptom of a few different things. I removed the fish to qt same day I saw this but she died the next day. I had a 2nd platy same exact events about 4 days after to the same end. Last week I pulled out a dead guppy and an oto with no signs of anything. All fish looked and were eating fine the day before looking pineconed or dying.

Now my surviving 2 guppys are "glancing" off the plants a notciable amount but no other symptoms and im wondering if I should treat the tank with anything and is so what should I use. (tanks also has 1 more otto, 4 pygmy corrys, 1 surving platy and rcs)

Things to add, might be relevent might not. I was on vacation for 10 days came back on the 5th of july, the fish were fed by my brother which I showed him how much and how often and the water tested normal that first day back before a 40% water change, but there was a noticble amount of decomposing leaves from my plants that needed to be removed and it was a heat wave not sure what tank temp was I was not there.

Any advise would be great even to just calm my nervs.

What are your water parameters? Sounds like something might be out of line.

Agreed.

I have yet to find a reason not to do a water change if any trouble is suspected though. I'd test and then do a 50%+ change. JMO

Tested the water 5 min ago same as it has been every test since I got back from vacation. Ammonia:0ppm Nitrite:0ppm Nitrate:15ppm Ph:7.5 been doing twice a week 30% water changes since the first death test before each one. Ill do a 50% now instead of the 30%, as recommended. Is there anything else I can do? Or am I at a just keep up maintance and see point here? Thanks for the quick responses.

Without knowing exactly what is wrong (if anything still or ever), I wouldn't advise anything other than pristine water conditions. Good luck and keep us updated!
