    Odd Aggression Behaviour.

    Over the course of a year absolutely no violent behaviour from the Jaguar Cichlid, until a couple of days ago where the Jaguar cichlid would non-stop continually attack an Oscar. The Oscar is now separated to allow it to heal. This is where the odd behaviour part of the question begins. I...

    Has anyone else had experience with their LauLau's [or other Brachyplatystomas] not necessarily going out of there way to chase/hurt other bottom dwellers, but becoming pretty territorial over a portion of the tank? Mine is around 6" and currently shares the bottom of the tank with two 8"...

    Black Diamond aggression

    Are Black Diamonds or Black Diamond hybrids know to be the most aggressive of Freshwater Stingrays? My Motoro and unknow Hybrid Stingray just swim around a little and hide in the sand a little. My Black Diamond hides very little and likes to climb all over the other 2 Stingrays.

    Hi I am in need of some help. I have an aggressive blood parrot, 7 in female. She won't stop harassing a red peacock cichlid I have. There is a 5 inch black convict in the tank, yes I know about the pH differences and it's a bad idea and stuff but they do completely fine together. The blood...

    Green Terror Trying to Spawn?

    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...

    Cichlid custody dispute among rainbow cichlids. Divorce pending?

    I have a breeding pair of rainbow cichlids who have successfully bred and raised fry before and have been together without incident for at least 6 months. Their latest batch of fry has led to a real mystery and something I never thought I would see with fish. The male has about half the fry on...

    When I first got my GHXB I kept him in a 4ft. temporary tank until his new 7ft (325g) home was ready. During that approx. month he was always quite calm and cool. However, since putting him in the 7ft'er he has become increasingly aggressive, especially towards nets or siphons and it's gotten...

    Bloody finlets

    I’ve noticed my albino Senegal with a few bloody finlets the past 2 times I’ve done a water change. I change about 75% of the water every 4ish days. None of the other polys or fish show open wounds. Wondering if the bloody finlets is from aggression (he’s the smallest poly) or potentially from...

    My rainbow's aggressiveness is no longer cute

    I have had a fully grown male rainbow cichlid for a year now and he's an incredibly aggressive fish. I have had Jewels, convicts, keyholes and firemouths and yet my male rainbow is FAR more aggressive than anything else I have had. He goes for my hand every time I put my hand in the tank to move...

    Pictus Catfish and Rainbow Shark

    Hello! I've been fish keeping for a while, but I've found I always come across more things to question. My rainbow shark, for one, has been difficult to accommodate, but he is worth the heartache in my opinion. He's much MUCH less aggressive than he was originally, since I took steps to calm him...

    An amazing video about the Kribensis (Pelvicachromis pulcher)

    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...
