I've had this nerite snail for about a week now, and all has been fine. The past few days he's been hanging out under the filter, and today when I checked him, I saw this weird white string coming out from his butt(? Idk but its the opposite end as his antennae)

Is it just weird poop or something to worry about?

Just wanted to show my 10 gallon tank I’ve been leaving to grow with no maintenance :)

Hello! I was hoping someone might be able to assist with diagnosing why I seem to slowly be losing my Molly colony…

They seem to get progressively more lethargic until I find them on the bottom not moving much unless they get startled then pass soon after. Some of them seem to have some white lumps that looks more like pimples/cysts, rather than ich, of various sizes. I have once seen larger one burst but was unable to find the fish again to take a photo.

Water parameters are normal and it’s a well established planted tank: Ammonia: 0 Nitrites: 0 Nitrates: ~30

I just started dosing PraziPro since the closest thing I have been able to find is possibly skin flukes?

Any help is appreciated!

The Guy in the Fish Store told me it was a male But i am Not sure.. he is really bloated and I didnt feed them much…

So I have 3 tanks running right now 1 30 litre tank for orange shrimp and snails (with one internal filter) 1 100 litre tank for just aquatic plants(first time so not putting fish in yet) and my main tank which is 60 litre and I’m currently running a tetra whisper 15-20 gallon per hour ,unfortunately I only have duckweed in this tank and artificial plants ,I have 8 guppies 2 cobies and one bristlenose pleco living in the tank ,I have a spare smaller filter that I used previously in my shrimp tank ,would it be okay to add it in beside my filter or is there downsides to it ?

My tank has been cycling for over 2 weeks and everything has looked good, the pH is maybe a tiny tiny bit high (little above 7.0) but everything else is perfect. I've had plants and driftwood since week one and got fish today. I acclimatized the fish in the tank for 30 minutes before using a net and getting them in the tank.

The corys are perfectly fine and normal, but the tetras are not!!! Since I put them in, they started exhibiting really weird behavior, they would swim around frantically and then go limp and not move for about 5 seconds. I turned off the lights and assumed it was stress. It's been about an hour and I just went to check on them and they are laying fully down on the substrate not moving. I can't tell if they are breathing. Did I just kill all of my tetras?!? My water temp is about 75 and everything else is normal what is happening!!!?

I just put my “sick” guppy into a hospital tank. He was swimming on his side I literally mean fresh water from the tap with aqua safe literally nothing else now he’s swimming fine?? I thought he had swim bladder I literally just spent an hour setting up a hospital tank. What do I do? Do I treat for swim bladder or not?

Little over a month ago I posted a photo of my tank with some stringy white stuff floating around (pic 1). I initially thought it was a type of algae, or something that bloomed from my leftover sand (it smelled like rotten eggs and I took out most of it a few months prior). Redditors said it could be hair algae. I dosed my tank with algae-fix and it seemed to lessen.

In the past couple weeks, green algae had taken over the spout of my filter, so the spores were spreading 24/7 (pic 2). Today I did a 30% water change, scooped up the algae carpet, rinsed my sponges, and scrubbed the filter spout. Then I started dosing my water with its treatments. I noticed the AquaSafe by Tetra was really visible, like pouring oil into a pot of boiling water. A few minutes later, I see the white stringy stuff again! So it's this water conditioner giving me issues.

Disheartened, because I've used this brand (pic 3) since the start of keeping an aquarium, 6yrs, and this is the first time I've seen anything like this! I don't think I'll ever buy it again. For now, I have to wait at least a week for this stuff to solidify so it's easier to catch and take out of my tank. I'll also continue dosing with algae-fix to keep the green algae at bay.

I have a 90 gallon tank, and I have 8 spotted silver dollars, is there anything else I should add?

Hello!! I have this aquarium hide that my ride just love, the rest of my tank is entirely natural wood and plants that provide hiding spots. I try my best to only use natural materials with my fish but they just really love this one basic plastic aquarium hide I got years ago. While cleaning their tank I noticed there’s some sharp edges inside the hide, I don’t want this to hurt them and was wondering if it would be safe to sand/buff down those edges with a dremel, then clean the plastic hide? I would just get rid of it but they really love it and would prefer to just make it safer. (Context if helps, I have a 50 gallon freshwater tank with 5 corys, 1 bristlenose pleco, and 1 rope fish. I noticed a while back the bristlenose had an injury which I quarantined and treated and he made a full recovery, but I suspect it’s from cutting himself on the sharp plastic)

Hello does anyone knows if those little balls on my betta are ich?

Hello everyone. I picked up this 125 gallon tank and stand from a friend.

As far as I can tell, the stand is built from 1/2 inch thick wood, possibly a hardwood since it was quite heavy. There are no 2x4s or other supports

With the way the sump is setup, I have to run the water pretty high so it will be a continuous 120 gallons or so. Making it pretty heavy.

Will the stand (given good condition) be strong enough to support this weight reliably? Any help would be much appreciated it's my first time with a tank this size.

I have two blood parents that I’ve had since they were the size of quarters. They are both together in a 200 gallon tank no problems with them all seem happy and healthy. One has developed white scales on its body. Not sure what it is. Need help figuring it out.

One thing that will never make sense to me is the school size advice that pet stores give, like 3 or less corydoras is fine. It just doesn't make sense wouldn't they reccomend the right group size (6 or more) so they can make more money and at the same time the buyer and fish get a better experience?

Right now I have a 20-gallon planted tank with LOTS of guppies, around 4 octo cats, and one black kuhli loach. Along with mystery and ramshorn snails.

But at PetSmart they have a 55 on sale that would fit very well where my 20 sits. I have till February to get it. Ill sell my 20 and everything that goes with it if nobody in the family wants it. (if anyone has pointers on how to sell on Facebook let me know, Id like to sell some of the guppies as well)

I was thinking about the types of animals id put in the new tank and would like your input:

guppies (shorter/round fins), kuhli loach (a variety), more octos.

Small Schooling species like zebra danios and neon tetra

And the crap shoot list; Borneo loach, golden wonder killifish, Corydoras catfish, bumble bee gobies, shrimp (I know that ones is a stretch).

I thought about striped Raphael catfish because I've had them in the past and they were pretty neat, just to have as a peaceful centerpiece in a tank with smaller fish. But the size concerns me with any of the species that likes to stick to the ground. So maybe a spotted would do better because its smaller?

Either way, I want to create a complex aquascape with many plants and hiding spaces. I purposely chose fish like the golden wonder killifish, zebra danios, and neon tetra so they could prey and fed off of the guppy fry.

Recently set up this 20 gal it’s about two weeks old. There’s this yellow algae growing that doesn’t look like any of the algae I’ve seen in my other tanks. It appears to only be growing on the glass. Does anyone know what type of algae it is or what it indicates about the health of the tank
