  1. Starting over due to bacterial infection… start tank over?

    Yes, absolutely. You understand me perfectly. Healthy fish carry harmless amounts of a variety of different bacteria and other microlife, and still others come in with plants or even just drift in in the air. Some fish are genetically weaker which is a problem exasperated by poor breeding...
  2. Starting over due to bacterial infection… start tank over?

    Surprisingly, no. The bacteria is natural and will always be in the tank. With no weakened fish to latch onto, any extra colonies will quickly die and will go back to low numbers that can't do any harm. Compare it to breathing in mold spores in the air (as they always are) vs breathing in a...
  3. Is anyone currently researching Lemon Tetras?

    No he definitely didn't! I had the embers in a quarantine for a week prior to adding them to the tank, on top of carefully looking them over in the bag before putting in quarantine. Also, I obsessively count my fish all the time (to keep track and make sure everyone's alive) so I know how many I...
  4. Is anyone currently researching Lemon Tetras?

    I ask because I keep them, and I've had a very strange development that would definitively answer a question that's been asked about the species. See this little guy on the right here? The red-orange lemon tetra? Yea... He was born in my tank, with all the others being normal coloured lemons...
  5. Help, columnaris or injury?

    I occasionally get 5ppm nitrate, but there's so many plants and just one little fish. I think she may have gotten stuck against some filter sponge, I had some of the rough stuff as part of a diy sponge filter which was a mistake :( I've changed it to the soft and rounded sponge now. There's...
  6. Help, columnaris or injury?

    Tank What is the water volume of the tank? 10gal How long has the tank been running? 10 months Does it have a filter? Homemade sponge filter Does it have a heater? Yes What is the water temperature? 79 then 77 What is the entire stocking of this tank? (Please list all fish and inverts.)...
  7. Help, columnaris or injury?

    What the heck happened to Wendy's back?? Is this columnaris or did she somehow scrape her entire back fin off?? This somehow happened in under 24 hours, please tell me it's not an infection.... What should I do?? More info: This is her tank, 0/0/0 for the nitrogen cycle and 6/7 for gH kh...
  8. Shoal starting to lose members to old age?

    I've got a tank that had 11 lemon tetras, most of which were at least 2 years old. Mycobacterium are firmly entrenched in my systems, so with their age I suppose Ive had 2 pass recently. The other 9 seem active for the time being, but quite a few of them are looking a little haggard. I'm...
  9. Oscar attacked by larger Oscar

    Mad respect. I hope your Oscar is doing well.
  10. Neglected Oscar tank- what can I do to help in 1 afternoon?

    I went to a restaurant I've never been to before today and they had an Oscar tank that immediately caught my eye. There's one Oscar and a common pleco in it. I didn't get a good photo of the tank, but here is the "little" fellow: I'm not sure exactly how big the tank is. I would estimate...
  11. Is this hole in the head?! What's wrong with my lemon tetras??

    That looks beautiful! I am definitely going to do that. What plant is that growing against them? I will look into those, thank you! I like the ones with the red, reminds me of my cpds
  12. Is this hole in the head?! What's wrong with my lemon tetras??

    That's what I'm thinking I should do with them honestly, they were never like this when it was more crowded in there (not that it was ever crowded, but they obviously need competition or they fight amongst themselves) Do you have a recommendation for another species? My ultimate goal is to...
  13. Is this hole in the head?! What's wrong with my lemon tetras??

    Unfortunately this is one of those things that can't be fully understood without seeing it. After having observed this particular school for a couple years now, I'm pretty confident that: their behaviour has changed; what they're doing is bullying; and the bullying is causing stress to the...
  14. Is this hole in the head?! What's wrong with my lemon tetras??

    Thank you for that, it means a lot to hear from someone who also keeps fish (hearing it from a partner with no real interest is kinda like having your mom say you're good looking LOL) I'll look into that food, thank you. When I make repashy (once every couple weeks for a couple days of food)...
  15. Can someone please identify this as a bacterial or fungal growth? From a light microscope slide

    Richard sounds awesome! Bettas are such angry Bois, surprisingly tho I think the females are angrier lol If you post some pics of your betta, I might be able to help tell you what's going on with it. I'm somewhat familiar with it now after all that with Flower. Here's Cassis, my imbellis...
  16. Is this hole in the head?! What's wrong with my lemon tetras??

    Thank you for the encouragement. It's frustrating because it seems like no matter what I do, I frequently have sick fish. This is the two lemons now, in better light: They are still acting completely normal, and happy and healthy as ever. Would the dark marks be hemorrhages? I don't want to...
  17. Is this hole in the head?! What's wrong with my lemon tetras??

    Thank you for sharing that paper. I read the whole thing, and I was wondering if you could explain one section for me. The part about UV light made sense for the most part, but this line threw me off: "Thus, if ultraviolet disinfection is used in aquarium systems, it is necessary to ensure...
  18. Can someone please identify this as a bacterial or fungal growth? From a light microscope slide

    Thank you for the enthusiasm! Someone on Reddit responded (I posted there as well) and told me that this wasn't enough to identify it >.> But I can give you the run down on what happened anyway. Also, it's fun to look at things from your fish on a light microscope lol. No idea what I'm looking...
  19. Is this hole in the head?! What's wrong with my lemon tetras??

    When I say I move everything around, I don't mean I literally move every piece every time- not even close. I mean I get the siphon (just the tube) into nooks and crannies moreso. Come to think of it, the only thing I really move is the hut decoration (since it's a poo trap). Everything else gets...
  20. Is this hole in the head?! What's wrong with my lemon tetras??

    This is honestly so weird, I have no idea why this is happening to my lemons. They've always been super healthy and happy, they spawn all the time. They were the first fish I got when I got into the hobby almost 2 years ago, and I haven't lost a single one until this morning when I found one...
