Ok, so I have had a 29 gallon tank for 6 months and it had a black piranha and a tiger oscar (RIP) and they got along better because they grew up together. I recently got a new 29 gallon tank, and I have 5 juvenile convicts, a juvenile oscar, and I'm getting 3 jevenile green terrors on friday. Do you think they will kill each other, or grow up happy? (I have added the third green terror and the fourth and fifth convicts in case of loss) Please let me know what you think.
