Mean SOB Neon Blue Dwarf Gourami

1947 4
I screwed up. I have 3 Neon Blue Dwarf Gourami in one 29G tank. I started with two, as I was a chump and trusted the kid at the LFS that said they were peaceful. The one with the brightest colors is a real mean SOB, first tearing up my guppies in my (de facto) quarantine tank, and now chasing my Cory Cats. I thought once he was in the big tank he'd be cool (like the Fonz), He's not.

Recently, at PetCo, while talking story with the Fish guy, we noticed what one of the Neon Blue Dwarf Gourami they had for sale was (very likely) female. She has all the hallmarks of female dwarf Gourami - fade colors, (almost no red), and a rounded dorsal and anal fins. I couldn't let this opportunity go to waste. I told him to bag her and took her home. Once she was in the tank she vanished into the plants.

He's my problem, I have two males, one shy and the other outright aggressive and one (very likely) female. My gut says that I should boot the jerk (with the great colors), and keep the shy male and the female. So one day I might breed them. Or really do I need to find new homes for all of them? However, maybe, I could find a new home for the shy, less colorful male and the jerk will cool down once he's the only male in the tank.

So I'm assuming I'm looking for a new home for aggressive Gourami, but what about the others?

Side note: I was thinking maybe keep one male and try to find more females. But I'm worried the color guy with his bad attitude would still be a problem no matter how many Gouramis I keep...

DG are normally (reasonably) peaceful fish, both towards other species and each other - but males can and do often get into it if they don't have enough plants or other cover to break up sight-lines and provide a refuge.

Now, if there is a female in the tank, there's a good chance that the overly aggressive male is staking his claim on her and a large chunk of the tank. If a male is ready to mate, it can become aggressive towards every other fish or critter in the tank. Have you seen him blow a bubble nest or flare at the female frequently?

You can add more females, just don't overcrowd. Generally, a higher female to male ratio works well for most fish - it helps prevent excessive male aggression.

So is he going to calm down, or do I have to find him a new home?


* The tank was planted just days before fish were introduced. While plants like the Amazon Sword are dominating one corner, the rest need time to grow.

maybe try and find the non-aggressive one a new home, he is clearly the less dominant, and if you like the colors more on the aggressive one and the others a female... you get the point, i'd either make more hiding areas and break lines of sight or dump the non-dominant one
