Hi everyone I have recently gotten back into the hobby and I am a bit rusty about certain things. Anyways I have a couple guppies and platies, but as you know guppies breed really easily and the fry are are now juveniles and starting to show colour so I believe that they will be fine in the main tank with adults. They are basically under an inch. However, I want to know whether I can expect some aggression on the juvenile males from adult male guppies and platies. The tank is 90cm long and has a reasonable amount of plants. Fish in the main tank include 2 adults guppies and 2 adults platies. All adults were bought on impulse when I was just meant to buy dog food. Haha!
