I am a novice aquarium owner, but I love my fish and this is my first experience with anything like this.
A little background:
-20 gallon freshwater tank
-up and running for over 2 years with no issues
-partial water change 2 weeks ago
-2 black neon tetras
-1 neon blue dwarf guarami added 2 months ago
- no change in food
-no other recent changes EXCEPT
On Monday (4 days ago) I received a pleco (not exactly sure what kind) as a gift (bought from a pet store). Two days later, it died. This morning I didn't notice anything wrong with my fish. Tonight, my fish are all covered with small grain-like white spots.
Unfortunately, I had previously planned to be out of town this weekend and have to leave the care of my aquarium in someone else's hands. Any treatment I will need to pass along to a friend so specific directions would be greatly appreciated. I haven't had a lot of time to look into treatment but I have read mixed things about raising water temperature or additives. The person caring for my fish will be willing to go buy anything necessary, but I only have access to a Petco. (I can order things online, but I'm worried they won't be here in time to save my fish).
Thanks in advance for any advice
