  1. 20 Gallon Tank Weird biofilm/algae in axolotl tank

    Tank info: 20 gallon long w/single axolotl, 2 sponge filters, 1 HOB, water changes every 1-2 weeks. Ammonia: 0ppm, Nitrite: 0ppm, Nitrate: 0ppm, pH: 7.5, temp: 64-66F This stuff is unlike anything I've had to deal with before! It looks like a mix of fillamentous diatoms and biofilm. It grows...
  2. Marimo covered in pest algae, best treatment?

    So far I've done two salt dips and the algae has dwindled but not gone away completely
  3. Marimo covered in pest algae, best treatment?

    Hiya! I'm taking down my old axolotl tank and I have three nice sized moss balls (zebra mussel free as I bought them years ago and want to save them) that are covered in black beard algae. The tank was also covered in hair algae. I want to make sure I don't introduce algae to any tank I put...
  4. Bleach Ratio for Decapsulating Artemia?

    I'm going to try decapsulating artemia cysts for the first time and I am seeing so much conflicting information on tutorials, especially when it comes to the amount of bleach used. Some say use straight 5% bleach, and others say 2cups water to 2/3cup bleach, 1:1 water to bleach, 1:2 water to...
  5. Weird marks on Oscar head

    Fish have pits in their face that help them sense their surroundings. Sort of related to the lateral line. Sometimes these become infected and begin to deteriorate, leaving larger pits and open areas. This is referred to as head and lateral line erosion. This doesn't look severe enough to be...
  6. Too many female guppies maybe?

    Is this a guppy only tank? It's possible that you have one aggressive female that does NOT want to be bothered by the males, but I would think there to be another culprit. I do not think you have too many female guppies, it's likely just one that's causing problems if it is a guppy at all doing...
  7. Fluval 2.0 Power Source: Alternatives? Need Electrical help!

    Hey all, I got two free fluval 2.0 lights a while back but both didn't come with the rest of the cord/plug/power source box. I really want to salvage these lights but all of the replacement chords are anywhere from $60-$100 each without the wall plug included. Is it possible to wire your own...
  8. What type of plant is this?

    It looks like an amazon sword 'compact' to me! They stay a bit smaller than your typical amazon sword.
  9. Help with guppy tail- fin rot? Or bite?

    Looks more like a bite to me. It's possible those fish could've bit him but usually those species are pretty peaceful. I would wait for it to heal on its own, it doesn't look infected to me, but if it recedes anymore I would treat with salt and possibly an antibiotic if it's bad enough. Melafix...
  10. Forktail rainbowfish mouth problem

    Doesn't look much like a worm to me, if it starts to look inflamed at the base of the protrusion it could be though. Sometimes fish get weird little growths or nodules on their lips. It can be caused by a variety of things, but if it doesn't grow or look infected/fuzzy, it's probably not a huge...
  11. Help please for goldfish and bare bottom tanks

    I see! So I'm sure you've heard about cycling on here by now-you're going to want to cycle this new aquarium before adding him, or by doing what is called a fish-in cycle. If his current tank isn't cycled, it doesn't make much sense to keep him in there while you cycle his new tank. In that case...
  12. Using rocks and wood from outside

    You can totally do this, but keep an eye out for a few things. If your rocks passed the vinegar test and have been rinsed off they're fine to put into the tank. I haven't ever heard of bleaching rocks being dangerous though, and have done so many times without issue. Do you know why that...
  13. Can somebody help me figure out what killed this fish?

    Very mysterious! My only thought is extremely low oxygen? Something the betta wouldn't be harmed by, but the acara would. The thrashing seems like it could have been freaking out because it couldn't breath. Just a guess though, this is very weird.
  14. Help please for goldfish and bare bottom tanks

    Sorry for the late reply-- The brown stuff is likely brown algae which is completely harmless and very common in new/uncycled tanks. As for the sand, I would wash it. It's usually pretty dusty unless it's the kind that comes in liquid (live sand). You can put it directly into the tank after...
  15. Help please for goldfish and bare bottom tanks

    You won't see any hydrogen sulfide if the sand is an inch or less deep, I would just stir it when you're siphoning the bottom. I use sand in many of my tanks and have never had an issue, even with hydrogen sulfide pockets occasionally forming in my deeper sand beds (3inches+). White sand can get...
  16. Something is wrong with my adf foot

    That would be perfect. You might want to put plastic wrap over the top and poke holes in it so your froggy can't climb out, I've had them escape through the smallest holes and they might be able to climb up a corner or on the heater wire. I'd just do frequent water changes on it and treat...
  17. Help please for goldfish and bare bottom tanks

    The sand should not stick together underwater, but in deeper sand beds you can get pockets of anaerobic bacteria which create gross black areas and hydrogen sulfide gas. I would do a thin layer of sand, maybe 1" deep, and stir it a little when doing water changes. In terms of food, as...
  18. 32 gallon tank planted tank ideas?

    I think the fish list looks great! Personally, I like clown plecos and rubberlips, a little smaller than bn plecos, therefore less poop :p Twig catfish are another interesting option if you like oddballs. Panda garra are neat too, but you'll want a group of those, they're a bit more social, and...
  19. Help please for goldfish and bare bottom tanks

    Of course! Happy to help! Getting into fishkeeping is hard because there's so much conflicting information and a lot of pet shops aren't very helpful or knowledgeable. In terms of water parameters, you should have 0 ammonia, 0 nitrite, and some nitrate. 40ppm is pushing it but goldfish produce...
  20. Help please for goldfish and bare bottom tanks

    The water cloudiness is probably due to the tank being a newer tank/having removed all of the substrate and not it being barebottom. It sounds like you're experiencing a bacterial bloom which will go away once the tank stabilizes. You may have accidentally impacted your bacterial colony by...
