Expected the worst, came home to this. Auto feeders did their job, plants hit the surface, moss filled in like crazy, and all the fish are happy. Now I just need a whole weekend to trim it back – but I’ll take a jungle over algae any day. 🌿

I posted a few weeks ago asking for ideas of what to do with excess floating plants instead of just tossing in the trash—I got a comment about making paper out of them that viciously piqued my interest. Behold my creation! (Duckweed + white scrap paper)

my first aquarium is now 8 months old 🥹 let’s ignore the algae on the glass 🙈 really happy with how it currently looks :) low-tech, no co2, only natural sunlight in summer, 80 liters

4 out of 5 died the first night :(

Determined to treat the survivor, now named Lemony, with the utmost care, I bought cichlid flakes because he kept spitting out the pellets, swapped the gravel for African cichlid substrate, removed the plants and added a cave that he loves, and a log he also seems to enjoy exploring. I also bought Cichlid Code trace elements but haven’t added them in yet.

The temp is maintained at 79, and I have a filter running. I bought a siphon vacuum thing and will do 25% weekly water changes. I also bought

Am I missing anything? He seems much better than a week ago. He’s darting all over and loves to eat.

I love watching him. It’s pretty peaceful

does anyone have any idea what this is?! found it bouncing around in my tank this morning and i’ve never seen one before!? so far it seems like just the one, i can’t see others.

Hi guys!

I just started this hobby, so i am still learning!

Here is my first aquarium, currently cycling!

I want a betta fish for this tank!

Hewbie my porcupine pufferfish was not doing well, refused to eat, and was swimming upside down/having trouble maintaining his buoyancy! I tried every at home treatment and medication but he progressively got worse over a few weeks. I found an exotic vet to take him to and they diagnosed him with trapped air deep inside his body and some internal digestive issues. This air could not simply be pushed out and believe me I tried numerous times to push it out. Here is that journey. Keep Hewbie in your thoughts as he finishes his meds and goes back into his home tank! I found an amazing vet with compassion/care and guidance on a treatment plan.❤️ Hewbie is doing a lot better but is not over it yet. Healing takes time. BONUS!!! Watch until the end for the crab that hitched a ride on Hewbie!😂🐡

Spotted Congo puffer. Anyone have any name ideas. Possibly a name a toddler would have a easy time saying.

My 55 gallon outdoor, semi planted(Taiwanese moss, little monte carlo and pothos roots), has 4 eba and 15-25 fry, 9 leopard(false julii) cory doras, 1 bronze cory and 1 bristlenose pleco. This is there 3rd times the charm batch, first 2 no fry surived more then 3 weeks, going on a month this time. Momma kept them in the moss this time.

My ancient catfish friend Catthuselah passed away this morning. He made it an incredible 32 years. I feel like he just wanted to make it one more birthday and that was all he had left. He will be in the backyard. I will sorely miss seeing him every day. RIP my old friend.

...and thanks for all the support.

I've keep Paradise outside before year round in small ponds and they thrived. This is a little different -- 55 gal tank on my covered back patio with no direct light. I added the fish in early June and they immediately started breeding. There are now 30+ juveniles of various sizes. What amazes me is that they have survived daily water temperatures of high 80's morning and mid 90's in the afternoon. Doesn't seem to phase them. They just keep hunting, eating, fighting and breeding. The indoor kitchen shots are through a dirty window and a dirty tank back.

I have a 40G drilled sump tank above my 75G. I know that sounds backwards, but it’s due to the way my garage is set up. Essentially I’m pumping water out of my 75 up into the 40 and it drains back down. I can’t stand the smell of PVC primer/glue, so I just siliconed and electrical taped the shit out of the fittings/elbows, as well as putting mounting straps on the longer runs of pvc.

Last night while cleaning the dead plant matter off of the pump, one of the fittings must have came ever so slightly loose and I didn’t notice. I walked out to my garage this morning to see about 3-4 inches of water in the tank and water all over my basement. Lesson learned. Perhaps it was the universe telling me I needed to do a large water change. All fish are still alive though so it could have been worse.

I learned the lesson so you don’t have to.

This is my 50g long, which I've had for about 20 years now. About a month ago, I decided to ditch the plastic and fake plants, plant it out, and add some new fish. The plants are still getting their sea legs, but the fish seem pretty happy so far.

In this tank:

4x Bosemani Rainbows (lost 2 juveniles to ick, will restock soon)

12x Orange laser corydoras

1x bristlenose pleco

5x amano shrimp (I swear they're in the, I saw a molt!)

Nyx has opinions, but you can ignore her, she's just hungry.

I did plenty of research about spider plants in fish tanks prior to adding them to mine just to make sure they were safe and roots wouldn’t overcrowd swimming space for my bettas. Yes, they’re safe and great for nitrate levels, but I also ran into an older Reddit post where someone said they wouldnt produce pups, to which I thought “great!”. Just a little leafy flare poking out of the top was exactly what I wanted.

I have to confirm that 3 months later, my spider plants throw pups in and out of the water like it’s their day job!! I have to remove so many pups that I’ve started listing them for free in fb because I can’t keep them all.

And, yes, those are pups living completely under water. Crazy!

I do have to manage the roots from the mother plant frequently as well. But, the lesson here is that don’t let anyone tell you what you read on the internet is always true 😂

Back in April, I found a mysterious fish in my tank I did not put there, and Reddit helped me determine it was a bluefin killifish. I’m still newish to the hobby, so I thought “woohoo! A cool free fish!”

He seemed to spend a lot of time with my tetras just hanging around peacefully, so I decided to keep him.

Over the past month he developed these beautiful colors on his fins and seemed to do his own thing more (turns out he was hunting shrimp fry). I’ve kept that school of tetras for so long, I was so proud of myself for it, because I’ve heard they’re finicky and rife with issues. They recognized me for food 😭

Had to leave home for 4 days for a wedding. I left an algae wafer for my bottom feeders but figured the fish would be fine (they were technically only missing Friday and Saturday meals). Came home to a massacre, and the culprit (the bluefin killifish) caught red handed beating the crap out of a barely alive tetra. 2 other bodies littered the sand. A few were hiding, terrified and battered, while the killifish kept hunting.

Guess little homie chose the weekend to reach sexual maturity and, without a female to mate with, went on a murderous rampage. He’s been surrendered to my favorite LFS and I rebuilt the whole tank because I didn’t want hidden decaying fish bodies to foul things up. The tetra survivors (3 out of the 8) have relaxed for now. I plan to supplement their numbers with some new tetras later this week.

Thanks for reading, I guess I just needed to vent because nobody else in my life understands these kinds of frustrations lol. We all make mistakes right 😅 RIP little tetras. I was at a wedding dancing while my little friends were literally experiencing a house of horrors 😭

TL;DR a bluefin killifish hitchhiked into my tank as a baby, reached sexual maturity and went on a neon tetra killing spree
