aggression

Hi, Ive got a 165 litre tank, currently housing all young fish. I have 2 angelfish, both too small/young to tell the gender, 3 mollies (1 male and 2 females), a clown loach and a small bristlenose catfish. Ive read that if the angelfish are both males, 1 will kill the other, if they are both...

Hi All, Tried my hand at salt water fish a few years back and let's just say I'm better off here LOL! Any how, I've had my 29g Biocube running for about 2 months now (recycled from the saltwater experience) About a month ago I stopped at Petsmart and bought some cheap fish in case any died in...

We just recently lost a female molly due to who knows what. No other issues in the tank, she just never grew then started acting completely strange and died. So we bought a Dalmatian lyre tail for our very large and "needy" black molly so he could have 3 females again. Mind you, he and the...

I need help or any tips or advice after the larger female spawned. The eggs are on the red rock. The behavior got worse after the the female spawned but started 3 days ago since I transferred them to the 90 gal tank. I purchased the younger male at a LFS in hopes of finding a mate for my...

I have a male betta fish that seems to be unusually aggressive. He likes to try to nibble my finger a lot when I feed him (he jumps). Also recently I cleaned his tank and removed all algae growing on the glass which probably lets him see his reflection better, so he flares his gills a lot more...

Hi I'm from MA, US. I've had fish in my 20 gal tank for about 5-6 weeks after it completed the 6 week ammonia cycle. Right now I have mostly Platys. 2 female Red Dalmatian, 1 male 1 female Blue Platy, 1 male 2 female Bumble Bee Platy 3 Panda Corys 1 Albino Brittlenose Pleco All has been...

Hey guys, I’m getting my largest tank yet soon, and I’m hoping I can snag a 75 gallon, but I’m having trouble finding one for a reasonable price. I’m thinking I’ll have to settle for a 30 gallon. I’ve completely fallen in love with my dwarf Gourami I received after a friend of mine couldn’t keep...

So I had a couple of Congo Tetra's for a while, and have now finally got 12 Neon Tetra. There are plenty of plants and hiding areas but the Neon Tetra's are very small and the Congo's being fully grown have become a decent size. After a few hours I saw one of the Congo Tetra's eating a Neon...

I have a betta fish named Thomas Jefferson & he's a very healthy fish in a 5 gallon tank, but everyday he flares his gills and gets into that betta fighting mode. I tried my best to prevent him from seeing his reflection too much, but he still acts the same. He lives with a nerite snail named...

I have a problem with my lampeyes. There's a bit of a story so apologies in advance... I had a few already, and a few months ago I bought some more, as I only had one of my original ones left - they were about 5 years old which I believe is a good age for a lampeye. A couple of days later a lot...

Hey all,   So as the title says, we woke up to a tank of five CPD's with one alive and the other four dead.  I feel bad because this is our first time keeping them and we got them anyway even though quite a few were dead in the tank from which they were purchased.  However, everything in the...

Hi! I've had my Ellioti Cichlid for almost two years now and he's gotten quite large, lately I thought my tank was a bit bare so yesterday I bought a bright Peacock Cichlid. My Ellioti is about double the size of my new fish and he's been beating him up since I've fed them this morning. Any...

     Hey there everyone, I am fairly new to having a tank and only getting the initial cycling process near the end now.. It was a fish-in cycle, with a couple losses on the way but not many.      I have a 29 gallon tank with 3 plants in it at the moment. Here's a picture:      Inside are 8...

So I recently began stocking my 36gallon bowfront and decided to go with a semi-aggressive theme. I added a pair of angels and a pair of bolivian rams to start with and everything was going great. I noticed my white cloud minnows were outgrowing their home in with my betta so I moved them over...

Hey, just a quick question for you who are experienced with Congo Tetras :) I have a school of 8 of them in my tank, 4 are male, 4 are female. I have been noting some seemingly aggressive behaviour of late. I am unsure if it is normal social behaviour or actual dominance.  What will happen is...

I had a small tail nipping problem in my 55 gallon and figured it was my skunk loach because they are known for agression and fin nipping, but i got rid of him a few days ago and it seems worse... As of now I have: 2 white skirts A 1 inch EBJD A 3 inch Blue Acara 3 clown loaches 3 corey cats 1...

Hi there. I have a school of 9 neon tetras in a 70l cycled aquarium - 5 of them have been in there for 2 months, the other 4 have been in about 2 weeks less than that as the LFS hadnt QT'd them when i went the first time. One of the original 5 has been obviously very domineering and chasing the...

I have a 20 gallon planted community tank. Fish include-   3 female guppies 1 male guppy 1 hifin molly 1 red-tiger platy 1 red-tail sand loach 3 julii cory cats 1 hillstream loach   I've had issues with fin tearing before that was attributed to an overstocked tank. The tank is fine now but my...

Not sure if this is an emergency yet, but would appreciate someone else's opinion before I head off to work at 12.30! Yesterday I got a male plakat betta in my newly cycled 30L tank. No problem there - he seems to be settling in slowly.   About ½hr ago I noticed in the 60L tank that there was a...
