I originally had 6 lemon and 4 rummy nose tetras in my tank but am now down to 3 of each. Having had so much trouble with the lemons I am not keen to carry them on as a species, and would like to change to something else, (am quite keen on a different type of tetra). how do you phase a specied out your tank? They presumably wont be happy in the abscence of 3 other lemons - would they be happy in the prescence of another type of tetra? I don't know any other fishkeepers, don't want to carry on with lemons but obviously have ot do the best for the ones I already have!
Thanks.
Thanks.
