My brother and friends did this

[GP]

Today, I got home from work, and I learned that my brother went fishing. He cought 13 fish, 3 bass about 1 pound each and some blue gills. To put this briefly, I found all 13 fish in my new tank. Third time replacing the water...

Is there any hazards I should be aware of?

How big is the tank ?

 

[Teelie]

Parasites, disease and fungal or bacterial infections right off the bat.

How long were they in the tank and what did you do with them?

 

[appleblossom]

aargh. It's time to buy a locking hood for your tank from the sounds of it

tanks size

 

[GP]

5 gallon. I already changed the water, cleaned the gravel by hand, and replaced with reverse osmosis water, and hand cleaned the filter. Should I still be cautious?

They were also in my tank maybe an hour tops, and I discarded them in my town lake...

Since they were only in the tank for an hour there probably won't be any problems, but in the future NEVER release fish that have been in your tank into the wild. If you have nowhere else to put them, kill them. Unless you are 110% sure they haven't picked anything up from your tank. The consequences of releases fish back into the wild like that can be too great to risk it.
