would his agression to his brother be cured a bit if I introduced another male or female as there are only the two of them and the big one chases the other one and is majorly stressing it i believe
if you can't keep more than 5 then only keep females together, they much prefer each others company. Platies aren't shoaling fish but they do enjoy there own company, four females to one male, but unless you actually want to breed i would give the males a miss all together as they harass both females and other males.
your lfs should happily take the males off you as long as they are in good shape, they may even give you store credit so you can change to females, i wouldn't say you are over stocked. All females is deffinately the way to go if you don't want to breed.
that suprises me. What is wrong with them if you don't mind me asking? Is it just that they don't get along? Try different lfs's as i have never had this problem before and i've kept platies for years and years. f they are unhealthy because they are nipping each other seperate them asap, if you can't find a tank elsewhere just buy a peace of perpex (£5 max) cut it to size, sand it and seperate the tank, alternativley take out the apple snails and add 4 females (don't do the if the males health is poor due to disease).
ok you clearly have a dominant fish,they need to be seperated asap. Don't take that rule to seriously, it depends on a lot things, what filtration do you use? how often do you do a gravel clean and water changes (what %)?
Hya ive kept livebearers for many years including platies and always i keep a ratio to three females to one male and i have always found in doing so the females dont sucum to too much stress as the male attention is very much spread out.Try a ratio of 2-4 females per male that will distract them lol.
