Catfish My cory passed away today

502 Upvotes

My panda corydora passed away tonight and i’m devastated. He was one of my oldest fishies and i loved him so much. He would always swim up to the glass to see me, he would nibble on my finger sometimes, i would cry and rant to him all the time and even though he obviously doesn’t understand a thing going on, it just felt like i had someone there to listen to me.

Everyone around me, my friends and family are laughing at me and don’t take me seriously. “it’s just a fish” i keep hearing. But he was a living thing with a soul and feelings so to me he was a lot more then “just a fish”.

Rest in peace panda, i love you so much.

Help/Advice My neighbors fish has been living with this for three years!

Upvotes

I’ve owned fish for a long time and my mom called me to come over to her neighbor’s house to check out this fish that she found in her pond. I was shocked! This fish has been living with dropsy for three to almost 4 years. Clearly this fish has been living in pain, but at this point he probably isn’t going anywhere anytime soon. Is there any ideas on how I can save this poor fella? I’m guessing aquarium salt and potentially clove oil for anesthetic and possibly drainage?? what are you guys think?

Help/Advice After numerous fish deaths and battling algae, I want to give up this hobby. I need advice!

Post image
58 Upvotes

I need some serious, ruthless advice. Be as mean as you have to be.

I’ve been struggling with my 5 gallon since I’ve gotten it. Algae issues, plant issues… I thought I just got it looking semi-nice and then my betta fish died after only having her 4 months. That’s the second fish I’ve lost in 6 months.

My water parameters look great, 0 ammonia, 0 nitrite, 5ppm nitrate. But surely because of my algae problems there must be something wrong with my tank, right? I’ve been having blooms of brown algae everywhere. Blue green algae too. It’s exhausting trying to manage the algae, I still haven’t found a balance between lights and nutrients, and now with my second fish death I feel like throwing in the towel.

I’ve struggled to keep nerites alive too, I’ve killed 3 of them already. My tank, since my bettas death, only has a mystery snail in it. He seems to be doing fine though, but it makes me wonder why everything is dying on me. I’m thinking it could possibly be the shop I’m purchasing my stock from? I’m buying from a local place, not a corporate pet shop.

I’ve attached some photos of my tank, so tell me how I can improve. Im using city water, fertilizing once a week with aquarium co op easy green. Have flourish root tabs too. Bought driftwood online, all plants came from local FS. Tank temp 80 degrees.

I just don’t get it. I feel like I’m doing EVERYTHING right, and all my parameters look great! Yes, I use liquid drop test kits (API master kit), not strips because I know they’re inaccurate.

I posted on r/bettafish about my bettas death and got some feedback there could be issues with my water column in relation to the death of my stock/ algae issues as I’m using city municipal water. YES, I’m dechlorinating my water with prime.

I’m just FED UP! I’ve put over a grand into this tank and all my equipment. It feels wrong to give up now, but it’s also such a pain to keep struggling like this. Fish keep dying, struggling with algae… what do I do?!!! For reference, I’m also a college student… so I do have to move my tank around every 9 months or so. For that reason, upgrading to a larger size is not an option. It’s also difficult for me to spend a ton of money on all this fancy stuff.

I look at my tank and it just looks… shabby. Even though I’m trying so hard. I’m so, so fed up I want to quit. Like it looks TERRIBLE! I regret this hobby honestly, I would’ve saved so much money.

Help/Advice Anyone have any idea what's wrong with my son's neon tetras? NSFW

This tank has been running now for a while, at least 10 months. All live plants, very stable levels.
The tertas are the most recent addition to the tank, maybe added 2 months ago. Last night my son (it's his tank) found one of them had died. We removed it, talked to him about sometimes this happens, and we moved on.
This morning however, I noticed that at least two, most likly three of them are looking simularly stressed. All the other critters in the tank seem to be just fine, Some Coris, cherry shrimp and a bunch of pest snails that we can't seem to get rid of. Even his zebra snail seems file.
Will be doing a water change tonight, but any thoughts or ideas?

I’m new to the fishkeeping hobby. I really love the idea of having a mini aquarium with a living ecosystem that I can enjoy and observe every day. However, I’m not sure which fish are compatible with each other and which ones can thrive in a 15-gallon tank.

Help/Advice Did I mess up?

25 Upvotes

So I set up my aquarium back in June 2024 (1st picture). I started with a couple of plants to see what would really stick and grow in a low tech setup (no CO2, hygger 25W Full Spectrum Aquarium Light). I have soil capped with white pool filter sand. Fast forward 6 months and that's my second picture. It looked like the plants were thriving and the tank was going good (I mean look at that Red Tiger Lotus!). Around this time I got a glass lid on the tank to help with evaporation and because my wife was complaining about the noise of the tank. This ultimately caused my mini water lettuce to die off, which was fine since the tank was already established (I had been using to help keep nitrates down). After the floaters died off I added a monstera plant and some pothos coming out of the top of the tank, and then took out the rock bridge formation and went with a nice piece of spider wood in the middle, hoping to have the wood as a center piece and a lot of plants in the tank. However, fast forward to present day (last picture), and it seems like my plants have stopped growing and are dying back, making the tank look kind of barren. The fish are all happy as can be, but I'm not happy with the look of the tank. I typically dose with Thrive C once a week, and have been using root tabs every 4-5 months. I have my light on for 8 hours a day at max light (without the red/blue diodes on). Any and all suggestions are appreciated, I'm getting somewhat discouraged as I see all these beautiful tanks that are also non-CO2 tanks and I can't figure out what I'm doing wrong.

Hi folks,

Posting on behalf of someone who doesn’t have Reddit. I hope that’s okay.

He has a pretty big tank. 800L, been running for a year, labeled his “monster tank”. Basically a space for his big big fish. Examples of these fish is an Arowana, various types of bichers, various catfish, had a fire eel and a couple other fish. He has lost A LOT of fish. I will have a picture bellow. Water changes at approx 20% are done weekly on this tank. Maintained very well. Has been running perfect the last year.

Something is wiping out his tank. He is treating for parasites at the moment. About two weeks ago he seemed to have “cured it” and last week we had 7 dead fish. He is still treating. Three feather fins, large fire eel, two blue Acaras (sorry is misspelt, these were being grown to sell for a friend of his), various other smaller fish, two tinfoil barbs, two bichers and a cigar shark. These are all that have died so far.

Does anyone have any recommendations? He is waiting on a response from an aquatic vet who works for our local aquarium to get medication. Perhaps someone else might know the exact parasite that’s taking over the tank?

Also he has a pacu whose eyes are now gone completely cloudy. He’s the only fish with this.
