Betta_dude

Ok, I moved my guppy, betta and 1 of my mollys(the smaller black molly sized one)My sail fin molly stays cause hes pretty aggresive even for a molly, he chases the tiger barbs. Im adding two more tiger barbs and three cherry barbs. I put the tigers in first and I will put the cherrys in later. they're getting along great, they are swimming together like the have been tankmates for years. What should I add next? Im thinking about a rubber lip plecostomus. The ottos didnt do so well, I have one out of three left.

Separate the Male Betta - his fins will get ripped to shreds by the other fish (especially tiger barbs) sooner or later. A 5 - 10gal similar to your Female's will be good!
