Hello Everybody, to be honest I also wondering about keeping my paros outside during summer period. In my 100L ( 1m long) outside the house tank was plenty of any kind of microorganisms – what if I placed there one or two pairs of paros..) I think I will take a risk in this or next summer period. I can imagine how fast will fry grow when 24h/day something is swimming around they mouth ..:) Aquarium is placed under some wood roof and it will be covered by some net. Small insects can fly thru this net (mosquitoes) but bigger cannot (dragonfly..)
Greetings!
