  1. Hi Everyone, I'm wondering if it's possible to ease some of the fighting between my two female gold dust lyretails. One is larger and constantly picking on the smaller one. They're the only fish in the 10 gallon planted tank. The tank was intended for a single betta who fell ill during cycling (he's ok now and back in his 3 gallon). The cycling process stalled after I took the betta out and it was recommended to me that mollies would help restart cycling, which they did nicely and without getting sick. Anyway, as I'm still working remotely and have the tank on my desk, the fighting is driving me nuts. I miss the calm of a betta cruising around just admiring himself and begging for food 😊. But the mollies are very pretty and active and I was thinking of adding 1 or 2 additional female mollies. Would this just give more "victims" for the larger one to pick on? Do they every stop chasing each other in larger groups? I'm guessing the smaller tank is probably not helping the territoriality and adding more fish could strain the bio load (though I do regular testing and water changes). I could try to return them to my lfs, but would feel guilty. So either 1) moving the tank out of the room so I don't have to witness the constant harassment, 2) splitting them up by moving the smaller one to another existing 10 gal with a betta, or 3), a few more molly peacekeepers. Thoughts? I should also mention that the smaller molly getting harassed isn't getting fin nipped or damaged, just chased into the plants where she hides for a few seconds and then comes right back out to nibble on stuff, gets chased back into the plants, repeat. The larger female is especially bad during feeding time.
  2. I've kept many species and seen aggression from almost everything, many non-pike cichlids, two types of dwarf pike cichlids, variatus platys, plecos, wild bettas, etc s ome of which have ended in major injury. Plecos in particular are pretty vicious fighting over caves in my experience. That leads me to think freshwater puffers might be getting get a bad reputation. I work with the hairy puffer pao baileyi (now paired up) who never had a fight since arrival in 2018, and seperately have the mekong river puffer pao palustris in a colony that has now been in the fishroom for a month or two. Are Pao puffers really total murder machines who need solitary confinement in all instances or are they the victims of a reputation that might be amplified by how the exist in the hobby? A few of my 6 pao palustris colony definately chase each other from time to time and give some quick though intense "mouth hugs". I would bet those are probably territorial arguments. They end fairly quickly once line of sight is lost and everyone moves back to the cave or plant roots they call home. My current belief is they arent trying to fight to the death since they are all doing well eating, exploring, general puffering, and there has been only superficial scrapes thusfar. Those arguments have become less frequent as they have settled into defined territories. The attached short video clip is from earlier and is the palustris colony's typical feeding response to frozen krill. They even feed with a bit of a pecking order and exhibit some personal preference for certain foods. I have also observed both of those behaviors in my hairy puffers. Is the reputation of the ambush puffers based on research, a built in margin of safety due to their cost and how they are sold to hobbyists, aquarium legend, something else ? Am I just lucky with the 9 individuals over 2 Pao species I've kept so far? What say you nerms?
  3. I've had two angelfish in a 40 breeder for a little over a year, purchased as juveniles. They've been inseparable all this time, and even now they are always together. However, I am guessing I have two males, as I've never seen any breeding tubes, and in the past several months they've started sparring quite a bit. I captured a little skirmish on video back in July and converted it to gif (see below). The fighting isn't constant, but does occur multiple times a day, and even still, they are rarely apart. There had not been any injuries either, until I recently discovered a small lesion at the base of a pectoral fin on the black angelfish. He's still acting normal, eating, sparring with the other angel, and still hanging out together. Am I seeing normal (or rather, unconcerning) behavior here, or should I separate them? I can move one to my 90-gallon no problem, so the only reason I ask first is because they hang out all the time -- don't want to cause fish depression and such.
  4. Hi all! Short version (tl;dr): Newly added female guppy immediately started harassing established female guppy, which quickly devolved into an ongoing fight with no one backing down. What is the best course of action? Full story: Our display tank is a 20g high, stocked with 1 female guppy (we'll call her the "old female"), 1 female platy, and 5 zebra danios. Everyone is very peaceful and gets along well. Tank has been running for three months, is fully cycled, and has lots of hiding spots and line of sight breaks (no live plants, but "lush" with fake plants). We've had another male and female pair of guppies in a quarantine tank for 4 weeks with no signs of illness and never any hostility towards each other. The female even dropped fry in the quarantine tank and the adults ignored them despite no hiding spots! So I finally moved the new guppies over to the display tank today, and after cleaning up for a few minutes, I came back to observe. The male guppy was exclusively and AGGRESSIVELY harassing the old female, who is close to twice the size of either of the two new guppies. The old female was mostly tolerating it, but trying to focus on her algae grazing. However, the new female was right there with them and she also started harassing the old female- lasered in on her and pecking at her sides. This continued for a little bit until the old female started fighting back, and then they went at each other for several minutes until I used my net to separate them. Unfortunately this was not a serious solution and the old female found the new female again and immediately went after her. At this point, I removed the new female and put her back into the QT. I also turned the lights off in the main tank for the rest of the day to reduce stress and skipped the evening feed. As far as I can tell everything has been fine since then. I tried to research female guppies fighting, but couldn't find much info out there- doesn't seem all that common. My best guess is that the male saw a large female for the first time and released a hormone explosion into the water, which made the ladies go bonkers?? My plan right now is to reintroduce the new female in a breeder box in the next day or two and let everyone get accustomed to each other's presence before the fully releasing her. Good plan? Is this normal behavior? Any other thoughts/suggestions? Thanks so much in advance to anyone who takes the time to respond. This is our/my first tank since I was a kid and I am super into it! I'll be happy to provide more info if needed.
