Ive had the 210 set up for about 1.5 years with the current fish (2 Dovii x Motaguense 6 and 8", 2 bifasciatus 6 and 7", 1 zonatus 9", 2 Carpintis 6 and 7" & 3 small cons. I am going to remove the cons. I have sold my 90 gal and need to either re-home 10" Managuense or place him the 210. I have had him in the 90 with a bigger Oscar but had to divide the tank from aggression. The Oscar would always start the fights the Jag would finish them. In the 210 the Zonatus rules the tank. I am hopping this will work but have my doubts, if any have done this please fill free to chime in. I'm even wondering if this will make the tank a little overstocked. This will all happen by Wednesday.
