I found little black bug-like things swimming in my aquarium with my guppie. I cleaned the tank and they have not yet appeared again. Does anybody know what they might have been. They didn't seem to harm my fish thank goodness. Any ideas?
This wasn't actually my tank, and unfortunately the little critters were disposed of before any photos were taken. We just really wanted to figure it out. Especially when there is only one Guppie that has been in the tank for 2 years-so that really wasn't a dumb question about it being pregnant. That was my first ? ( unless I'm dumb too) The only other thing in the tank is a resident snail that has been there for 3 years. No real plants. I was just hoping it would be more obvious to you pro's out there, but alas....that is all the background that I have for ya. Thanks for the help everybody!
Probably came in on some plants... if it looked like little round brown/black dots swimming around in "hopping" fashing, it was probably daphnia. But yeah, you need more description in terms of size... could you see the legs... etc.
There are a lot of little "bugs" that the fish like to eat.
