HI all. I just recently decided to become serious about the hobby and thought this would be a good place to ask questions when needed, and eventually help others. I have a small 3gal I plan to keep just 1 or 2 small fish such as tiger endlers in just to start. To get my cycle going, I bought some guppy fry at my local pet shop. All is well and the guppies have survived about a week or so with no issues so far. Today as I went to check up on them and test my water, I noticed one was missing. I’ve checked inside my filter, under all the decorations, around the tank, and there’s no sign of it. I had 5 of them, now 4. Could the other guppies have killed it ?
