aggresion

I have a 5 in or so Oscar, I posted about him a few weeks ago when he had larger tankmates huddling in the corner. I got him a 90-gallon tank to get him out of the 55 gallon. I also decided that I wanted to try him out with a bigger tank mate in it. So, I choose a gold severum that I've had for...

I have a large tank, 350gal or so (not exact) and I want to add new fish to it, the problem is, there's a jag cichlid in there. How would I add more fish to the tank? Also, are adding more cichlids possible? I'm considering a carpintis/texas hybrid.

Hi all, So, the first three days the Firemouth just followed the Green Terror with no chasing of anytime, he seemed quite scared really. But it's been two more and he will not stop terrorizing him, just constant chasing. Is it supposed to be fun for them? My first time owning Cichlids and...

Hey I have set up a 90 gallon planted tank and just added some boesmani rainbows (6) and they all been nipping at eachother for a week. I have added aquarium salt to help heal their wounds but it seems to be getting worse. they have been in the tank for a week now and this morning I noticed one...

So a week or so ago I posted asking if my GT was male or female. Got mixed responses so unsure where to go from here. Although, GT has just cleared out a spot and is guarding it ferociously, even attacking me when I get down to look st the spot. It is completely on the other side of the tank...

Is it safe to introduce my new Green Texas and Blue Acara (half an inch at most), into a tank with 1 1/2 inch convicts (breeding pair)? The convicts are already circulating at the bags, as I'm acclimating. Anyone, have any tips on introduction, of new small babies into a tank while avoiding...

My new BEAUTIFUL Jaguar Cichlid!! So happy welcome to the family Jet!

So I'm going to get to the point as fast as I can. I had a 5inch Oscar, 4inch GT, and 6inch Senegal Bichir in a 75 gallon tank. They were in like this for a few months and only the GT and Oscar fought for the first two days and were completely okay after that. Two days ago I came home to a...

Hello everyone, I have created a 400 gallon concrete pond (6'X3'X3'). I want to stock some predator fishes. In my LFS there are some spotted gars (18inch & 3-4inch), silver arowana (5-8inch), small RTCs (2-3inch), Oscars (small to large). Besides this I have also raised 2 Oscars from baby to...

If my red tail bala shark had teeth it would be by far the most agro fish i have. It is already i reckon it just cant seem to hurt anyone. How big have your bala sharks gotten? Go ahead n show them off

So I've had one female oscar 14" for going on 7 years now who has been completely intolerant of any tank mates (except for the logdweller catfish) her entire life. about a year ago she laid eggs for the first time and stopped eating feeder guppies so I decided to to try out a school of 10...

Hello guys, So i purchased a 5-6" Male SRD Flowerhorn from a reputed shopkeeper. He is in a 50 Gallon barebottom tank by himself with a canister filter. I have a little cave too where he can hide to make it feel more comfortable. I bought it 2 days ago and the shopkeeper...

So today I went out to purchase some Mollies or Swordtails as @duanes, @dan518 etc suggested. So I go to my LFS and let them talk me into purchasing a chocolate Cichlid instead as they kept saying they aren't comfortable selling me Mollies etc with a JD. So I got the chocolate... I think I have...

I picked up a female opaline gourami a few weeks ago and it's a bit agressive, iv seen it chase some of my other fish and I believe it took a chunk out of my platies tail. I really like the gourami I think it's a good center piece fish but I don't want aggression in the tank. Can I do anything...

Hello, first off let me start by saying that I know the conditions aren't ideal. But it's a better life then previously for now. I have acquired an African cichlid (supposively) and it's only like an inch or two long and the previous owner said it barely has grown for months. Anyway for now...
