aggression

Hi guys, I’ve been following MFK for a while now and recently became a member so please forgive me if this thread is not in the correct place. If been pondering this question for a long time and I’d be interested to see what y’all had to say. Situation A) What fish would you say would be...

Okay, so, I've absolutely never seen this before - but I recently just bought a pair (Male and female) of kirbensis cichlids for my 29 gallon community. I have had a school of 6 diamond tetras for since I got the 29 up and running, and the leader of this school is the biggest, flashiest diamond...

Hi, was hoping to get some opinions and/or advice on my latest tank issue. We have a 6ft tank which currently has 2 oscars, (about 7 and 10 inches) 3 largish silver dollars, 1 female convict, 1 Pundamilia nyererei and one synspilum (about 10 inches). I don't know what sexes any of them are...

The Kribensis (Pelvicachromis pulcher) is probably the easiest cichlid to maintain and breed. In fact, due to their small size ( 3-4 inches / 7.6 - 10 cm ), hardy, adaptable nature, and ease of breeding, this fish is probably the ideal cichlid for anyone that is taking their first steps into...

My smaller female moke (moke 1)has been sitting in the left hand corner of the tank almost all day today. I saw her on the right side of the tank for a second. But the larger moke (moke 2) had the smaller mokes finlets in his mouth again. Moke 2 is so gentle, so it’s very bizarre. Over the past...

I'm sure this has been asked before but the search if failing me. The two oscars are still just babies in a 125 gallon tank. The tiger oscar is just a tad bigger than the my albino and he's the aggressive one. Yesterday I introduced 6 Zebra Danios as target fish. (I'm aware that they will be...

Here's the link to the thread: http://www.reefsanctuary.com/forum/index.php?threads/advice-on-a-hippo-tang-vs-blue-throat-trigger-conflict.82652/ I looked and saw other people doing this with saltwater. Does it work in freshwater? SOB fish + a mirror or few self portraits = model citizen?

Has anyone ever kept 5 bar lamprologus before? I hear they are super aggressive and will kill anything during breeding. I have a 5ft, 100gal tank, and plan to keep a few (6) with my 2 polyptrus seneglaus and group of 5 cuckoo synodontis. In the experts opinion will this work? Will they kill my...

Hello, I have 5 red belly piranhas in a 125 gallon tank. I bought them 2 months ago and 2 of them are growing exponentially faster than most they are 3 times the size of the others. (Got then when they were a half an inch) I can tell the other 3 are honestly just not growing like normal ...

So I recently bought a juvenile Red Texas and he isn't eating in front of me, and I can't tell if he is eating at all. Is there a way that i can make sure he eats? Also, I have seen him go at my other fish in the tank on his second day, so that brings me to my second and final question. Is he...

I've had a African cichlid (assorted African tank at petsmart) in a 5g all by himself for two years. The cichlid is light blueish/purplish and about 2" long. I wish I knew what I know now before I bought him. Anyways I have a 20g long tank with only a green phantom pleco, he's about 5-6.5" and...

So I have a male and female dovii both about 6 inches. They got along for a few days then the female went ape **** on my male took some fins and left a gash. He is healed up now and I have them separated with light defuser. I figured since the male is not aggressive with the female I just need...

This little guy has been terrorizing my entire tank full of cichlids and has nearly killed A flowerhorn and a green terror.. I'm trying to figure out why it only chases and trys to kill only the females in the tank but yet only allows the female convict anywhere near it. I thought it was a male...

Hello forum! I'm new to Monster Fish Keepers but have been a member of the Planted Tank forum for quite some time. I recently aquire 3 juvenile blood parrots that I am currently housing in my 29 gallon moderately planted tank. I'm having some issues that hopefully you guys can help me with...

Hello, I recently got a green phantom to get pleco and put him in my tank with a 5" kelberi peacock bass, the pleco is just about the same size. I know long term this won't work and it's only for a little while. Anyways the kelberi keeps swimming towards the pleco whenever he's out of hiding or...
