Hey Guys,
I am new here and i have three RES with me. I have a smaller tank now. Two of the turtles get along pretty well but the third one which is a female i presume (Since it is bigger) does not get along well. Do i need to separate that from the other two turtles.
Secondly Please suggest me a filter for a 35 gallon tank. I live in India and Boyu filters are not easy to get. I prefer the external Filter. Please suggest me which filter would be best to use.
