Hi guys,
i need a bit of help. as some of you know i did have 3 oscar fish (olly) who passed away (R.I.P)and it left us with 2 oscar fish.
now i have oscar who is about 6 months old at 7.5inch and ozmo who is about 4 months old and 5 inch. these 2 were very aggressive towards each other once olly died but over the last few weeks have started to get along and i noticed they are swimming side by side witch is great. question is we want to get a few more fish to add to the tank and we were thinking about chilards? questions are..
1. Is this a good idear?
2. Should they be around the same size of our oscar fish or is it to much of a risk getting babys about 1month old
3. if we do get new fish will it upset our other oscar fish they MIGHT be pairing?
4. is there any other fish we can get that the oscars wont get aggressive towards or eat!
and 5. our tank is 4ft x 3ft x 3ft is 2 oscar fish enough?
sorry i am new to the whole oscar fish and both my partner and i spent an hour in the fish shop trying to figer out what to do.. ended up leaving and thought i would see what you guys think since you all are very helpful

so any help or advice would be great

thanks bec
