Question

Aggression Issues


Alright everyone, here are tank specs as well as a list of inhabitants:

Tank:
30 gal
moderately planted
nitrates: 10-20
nitrites: 0
ammonia: 0
pH: 7
temp: 78

Inhabitants:
Male Honey Sunset Gourami
Male GBR
5 Gold Barbs
15 Green Neons
2 Zebra Loaches (need more I know, LFS is out atm)
3 Otos
2 Mystery Snails

My situation:
I've had this tank up and running for about 6 months now and have had ZERO issues as far as health of the tank and fish. Lately in the past week or so I've noticed my GBR becoming increasingly aggressive towards my loaches (who are both bigger than he is) which results in the loaches hiding pretty much 24/7 unless to feed. The GBR has been in the tank since the startup, while the loaches have been in there for about 1.5 months. Before the GBR didn't seem to care about the loaches, but now will hover over their hiding spot just waiting to attack. Is this a territorial issue? I have quite a few hiding spots in the tank but could probably use more. My GBR is a pig and can be aggressive towards other fish (everyone except the gourami) during feeding.

My question to you is: would more plants/hides help? Would more loaches solve this issue? I plan on adding more loaches anyway, but wondering if this would help the aggression issue? I don't want to add fish that will just be stressed. Is rehoming my only option? What do you guys think? TIA for any help/suggestions!

I would rearrange the tank. By moving stuff around, you can sometimes fix territorial issues (if that is the issue). More plants and hiding spots are always a good idea to curb aggression.

I wouldn't resort to finding him a new home or adding more fish just yet. I usually only get rid of fish if they are causing physical damage to others, as some aggression is almost inevitably a part of any mixed species tank.

Get the GBR a buddy. But like what Indychus said, as long as there's no damage, the fish are most likely fine. There will be some chasing, thats normal, but as long as you don't see physical damage, its probably just chasing.

I haven't seen any physical damage yet so I'll just keep an eye on them. I plan on adding more plants next week (waiting for payday) and more loaches when they become available. The GBR actually is good buddies with the Gourami, always following each other around the tank scavenging together, kinda cute actually. I wanted a pair of GBR originally but worried there would be more aggression issues if they decided to spawn in just a 30 gal. Thanks for your inputs!

i agree try to rearrange the tank. it will be like new to them so should in theory stop the problem and yes add more hiding spots. black pvc or bamboo make good places for loaches and they blend in to the tank so not seen as much say white pvc tubes

In my female betta tank, I started by adding them in 15 min intervals starting with the shyest up to the most aggressive fish. The last one which was pretty aggressive had to get floated in a clear container for a couple of weeks, she finally tired of trying to attack through the container, when I released her she was fine for a few days then started to get mean again so I gave her another timeout for about a week. No problems since.
A good re arrange is also a good idea to reset the territories.

I think I'm going to try adding more plants first, then if that doesn't work I'll rearrange. I really like my scape and don't want to redo it if I don't have to...
