r/freshwaterfish

I posted a few days ago about losing about a fish a day for the past week. The problem continued, despite my best efforts. My kids are crushed-I’m hoping someone here can guide me (I’m new to this) on what to try next.

Tank is a 75g freshwater, properly cycled (fishless). Water parameters continue to look good and stable. Have a Fluval 407 and I increased surface agitation because I was worried about oxygen (the angelfish like to stay at the top, but nothing else does). Tank temp is a stable 77.5 degrees.

Tank was stocked with angelfish, Cory and upside down catfish, neon tetras, Congo tetras, emperor tetras, and ram cichlids.

Losses have been across species, except the neon tetras and ram cichlids remain healthy. I lost my first angelfish this morning (my kids’ favorite fish!).

I had suspected aggression previously, but I think that’s less likely given losses across species. Now I’m wondering if there is some undiagnosed issue with the water, or some disease?

Does anyone see anything alarming in the attached video that can give me some direction?

Thanks,
Bill

80L/planted/6yo. The tank was the last gift my dad gave me before passing away; the hobby I inherited from him; he taught me everything I know, starting with how to love your fishies.
I just wanted to share :) (I like that it looks “wild and natural”, not extremely trimmed).

This is a 20 gallon bow front tank. It has an ac20 with purigen and a small sponge filter. Also running c02 and a small power head to add a light current for the white clouds and panda garra. I keep the tank around 78-80 degrees. The ph is around 6.3, ammonia nitrites nitrates always zero.

I have:
10 white clouds
6 otos
5 kuhli loaches
Some shrimp and pest snails
A queen arabesque L260 pleco
A panda garra
Two small German rams

This tank has been very low maintenance so far, and the only sickness or problems I’ve had is with German blue rams from bad stock. I plan to get larger tanks when I move to a bigger space, but that won’t be for about another year. Is this tank ok/humane for my gourami for that time period? Thanks

Iv had tanks in the past growing up never had issues of cloudy water or water imbalance it’s also my first time using live plants in my tank water was clear for about 5 days or less then went really cloudy it has been bouncing between getting better and worse never had this issue and don’t know what to do help rn it’s not as bad😭

My first ever pair of German blue rams!
90L high tech community aquarium, had it for 4 1/2 months now!

I’ve had this tank setup for a couple days, has now had a betta in there for about 72 hours. Not doing a fish-in cycle by choice! Not my first method at all ( it’s a longgg story will explain if someone really wants to hear it.) I just want peoples best advice. Not necessarily new to the fish keeping world but not EXTREMELY knowledgeable.

The tank is planted. Has fluval stratum then aqua natural bio substrate said to have live bacteria to help kick the nitrogen cycle. I also have a beneficial bacteria pouch, driftwood and leaf to release tannins. API quick start, obviously water conditioner/stress treatment. I have some seachem products on hand in case as well. Temp is around 78
It’s a 6 gallon tank with a hang on the back filter. Would like to change it to a sponge once tank is cycled because the filters where bacteria is living.

So far I’ve had no ammonia spikes but wondering if I will even be able to see one due to all the bacteria I’ve added when setting up and the live plants.
Hardness, kh, and ph are all fine.
Nitites nitrates and ammonia are all still 0ppm. Do you think this tank will cycle faster considering the things I have added? Obviously all tanks don’t have a specific amount of time.

Any good advice is greatly appreciated and your personal experiences cycling tanks well with fish or no fish welcome too.

Does anyone notice if something is off with my Kuhli loaches? I have read a lot about how to tell if they are stressed/sick and I’ve seen with the shape of them as well as color fading can indicate something’s wrong. But I genuinely cannot tell if they look more pale or not or skinny since I haven’t seen them before owning them myself so it’s hard to compare. I am new to fish keeping and LOVE my guys sm I just want to make sure they look healthy

Started a 6 gallon cube, maybe a month ago, it was a bit before Easter I believe. It doesn't have a filter bc I wanted to try Walstaad and bc im broke but it has a heater and proper lighting.

Water parameters rn:

Nitrate 0-5 ppm

Nitrite 0-.25 ppm

Ammonia ~0 ppm

pH ~7.6

It's currently stocked with bladder snails (hitchhiked) and two assasin snails. There's a good amount of micro fauna and a whole bunch of detritus worms but I only ever see them on my floaters and driftwood. Also Roberto the Ramshorn but I have no clue where he came from.

Today marks 14 days of my first tank, I love how it looks! It’s about mid/late cycle currently nitrites still need to go down but ammonia is 0🥳 the only algae that I’ve come across is a day or two ago I started getting brown dot diatom on glass. (Tank is crystal clear just some Co2 bubbles flowing around)

Setup:

30 gallon tank

Oase Biomaster thermo 250

15 lbs fluval stratum/ 8 lbs bio stratum capped in UNS Mojave extra fine

Pressurized co2 6.5 hrs day

Hygger programmable full spectrum light. 60% 6 hours a day(upgrading to week aqua light)

Very light doses so far of thrive+ fertilizer

Used seachem stability first 7 days

Purigen and filter floss in filter

50/50 RO and tap mix

Hi everyone,

I added a male/female pair of Honey Gouramis to my community tank about a week ago, and I’m a bit worried about their dynamics.

The male is frequently charging and chasing the female around the tank. Luckily, my tank is heavily planted, so she has plenty of dense vegetation and hiding spots to break the line of sight and get away from him. When she hides, he usually drops the chase.

For those of you with Honey Gourami experience:

Is this normal territorial/breeding behavior during the first week or two while they settle into a new environment?

Will this aggression eventually calm down, or should I be seriously worried about her long-term stress and safety?

They both still come out to eat, but I want to make sure I don't need to separate them before things get worse. Any advice is much appreciated!

Now I don’t really know how to correctly cycle this tank, I’m thinking of putting 6-8 black neon tetras and 6 amano shrimp. It’s a 20 gallon long since it was the only 20 gallon tank that could fit in the desk. I’m using a fluval 207 set to half flow with a spray bar facing a little up towards the back glass to lessen the current. I added an Amazon sword, some Anubia Barteri and some HC Cuba which looks rough since it was in a mesh before I took it out. Any advice on what I can do next?

- Veilfin tetras
- Thicklip gourami
- Bristlenose pleco

Your opinion? I decided to downgrade from a 80cm tank due to less space in my current living sitch. I found a lot of information on here before purchasing this, so thanks 🖤

this happened a few days ago i have no idea what happened can anyone tell me what it is and what i can do to help

includes Anubias Gigantea, Anubias Barteri Broadleaf, several bacopa including yellow flame and Salzmannii Purple, Rotala Orange Juice, Rotala Red, micro swords, argentine swords, crypt, Vallisneria Asiatica Biwaensis?, pogostemon, Dwarf Lily, and Java Fern.
