It should be Ok to have an airstone on the bottom of the tank with bubbles coming up, my fish sometimes swim in the bubbles but others keep away, this is not a problem though.
I was wondering if I could have a Puffer Fish in a TYropical Tank, I se you have some in yours do they get on OK, I just posted about this subject then I saw your post, please reply as my daughter would love us to have a Puffer Fish, Thanks.
Hi. I have just set up a tropical aquarium, I have guppies, neon tetras, platies I wonder can anyone tell me if I can get a Tropical Puffer fish to go in a tank with my other Tropical Fish??
