Hello all. In my 125 gallon i have one 3" female Festae, one 5" female Dovii and one 12" Oscar. Recently *** been thinking of selling the Oscar so please keep that in mind. Now with the Dovii and Festae....will these two REALISTICALLY be ok in this tank for a long period? Also if i do sell the Oscar is there anything i could put in to replace it.. Same with if im forced to sell the dovii. What else could work with the festae...NO BREEDING PAIRS PLEASE. Also i say realistically because sure female dovii can get massive, how ever doesnt mean itll happen to all of them, or happen fast. Also the Dovii isint overly agressive to most fish, how ever a black belt i had seemed to rub her the wrong way, so he had to go. The tank also sees weekly water changes and has three aquaclear 110s. Thanks for any help.
