. They are currently in a planted 20L cycled tank (but reading from other topics here, I might need to upgrade 
) They are doing quite well and no aggression to each other yet. They are quite active and exploring the tank for food and such. They look so different from other puffers, they are slimmer and don't seem to sleep on a surface like other puffers. They just float still like other fishes. Either that or I just never see them sleep because they are so active 
Anyway, I'm working on upgrading their tank and trying to breed snails for their growing teeth. But just in case snails aren't enough, I was wondering where I could buy this product Finquel so I could perform puffer dentistry? Is it available in local stores or do I need to order it online? Will nail clippers be ok to use on them? Can I feed them crayfish for their teeth? The crayfish that my LFS sell are about 2 to 3 inches big, I don't think my puffers could take on that big of a crayfish.
Now my tank is right in front of my air conditioner, but the air blows upwards over my tank hood. At night, when the lights are off and the AC is on, the temp goes down to 74 deg F. During the day when Lights are on and AC is off it goes up 78 deg F. So it goes down about 4 degrees. Will this cause harm to my puffers? In the wild the temp goes down at night right? So maybe it will be ok? My room is really small so I have limited space when it comes to moving my tank set up. But if it will cause any harm on them I'll probably just move it into my living room. The heater is placed next to the filter where the water flows, will getting a stronger heater fix this problem? The heater I have right now is for a 20gal, if I get one for a 30gal will it able to maintain the temp even at night?
It might take months for me to set up bigger tank, I have a tight budget, but hopefully they will be ok together for now. What would be recommended tank size for 2 modestus puffers?
Any other suggestions or tips for these awesome puffers would be appreciated
