[Strange guppy]

Sounds very strange, could have been a brain tumour causing irrational behaviour?

[New Fish for the Week 4/18-4/24]

Decent Batch👍

[US Native Fish Moment…]

Rainbow Shiners?

[How many fish? 120 gallon]

The Oscars should be OK, just keep an eye out for aggression 

[What are your favorite fish species?]

Thank you for so many great replies!

[Any Tetra Breeding Suggestions?]

OK Good Luck 🍀 

[Any Tetra Breeding Suggestions?]

Thanks ! Would you be able to recommend any other species?

[What are your favorite fish species?]

Hello all, as a “novice” aquarist, I have been keeping fish for a year, and I just thought it would be fun/cool to connect with others.

Favourite species to breed, keep, or enjoy.

[How long does it take for mystery snails to grow big]

If you wish to make them grow faster, I would suggest adding Wonder Shells or some other calcium rich substance

[Apistogramma Cacatuoides or Black Rams?]

Black rams are often way more aggressive to each other than normal German blue rams. 
Looking forward to see what you end up breeding!

[Behavior changes in Pea Puffer]

Have you fed him any different foods?

How long have you had him?

[New to the hobby, just saying hello]

@Fishfolk, what are the yellow and red tetra-like fish called?

[Sturisoma Breeding]

Thanks 🙂

[Sturisoma Breeding]

Would anyone have any Sturisoma breeding advice (eg. species, water parameters etc)?

[Any Tetra Breeding Suggestions?]

I’ve just started conditioning some XRay Tetras on live baby brine, and what do you mean by lighting trigger?

[Any Tetra Breeding Suggestions?]

OK Thanks 🙂

[Any Tetra Breeding Suggestions?]

Would anyone have any good suggestions for tetra species which are relatively easy to breed ?

Thanks🙂

[Help me troubleshoot shrimp deaths]

Planaria

Dose with Expel-P

[Are there any fellow aquarists in Switzerland?]

Thanks so much!

[Diamond Tetra Breeding?!]

Sounds like breeding behaviour because he's vibrating to release sperm onto eggs. Just keep an eye out for aggression.

[Aquarium Sand under a Microscope]

nice idea

[Are there any fellow aquarists in Switzerland?]

There are very few people in Switzerland who have an aquarium, so it would be nice to trade specimens and knowledge with those who do. 

[Fin rot or fin loss]

From The previously black edges you're able to tell that it's not fin rot. Does he have any tank mates, if so, what species? It looks like he has been a victim of fin nipping. How old is he? 

High Nitrite and Nitrate can (in my experience) cause physical damage to a fish, live plants can help to reduce those.

High lighting can also be problematic.

Best wishes

[Cancer, virus, or....?]

Jeez! I'm sorry but I've got no idea. Nice name: Kronos.

Best of luck.

 

[Cancer, virus, or....?]

If it's a virus, try Expel - P and see if it makes any change. Try slowly lowering down the ph (ideally to 6.2 - 6.5) to potentially kill it if it's a disease.

On second thoughts, it looks quite like a cancer; so it may die. 😔

The cancer may be genetic, so try not to breed the fish until the condition has passed, or...

Best of luck
