The betta fish (Posideon) doesn't eat his food. And if he eats it he immediately spits it back out. And he is getting reddish.

Hi all i recently just got my first tank in September. I had comets in it for the longest time. About a month ago I added 6 mollies And 3 corys. on the 26th I removed the comets (as they were too large) and I’ve had 2 mollies die on me! I also added some more water as the water was getting low...

Good Evening All. This is my first time seriously keeping fish. I bought a 10 gallon tank from petsmart. The full starter kit from Top Fin. Came with a heater, filter/pump, thermometer, and light. I put gravel at the bottom (off hand I don't know the total amount but it was the recommended...

Whats up everyone! So a little background info on my tank first, I have a 40 gallon freshwater tank. Its been up and running for about a month now with what appears to be proper water conditions. I started with 3 Green Tiger Barbs and 2 Tiger Barbs for a total of 5. Things were going well fish...

Hello everyone, I'm hoping to get some help! This all started in my established (about 7 months now) 30g tank. Mid last week I did a 50% water change and vacuumed the gravel per usual. A couple days later I brought home 2 guppies and 4 ghost shrimp. I added them after acclimation and things...

So here's a little history. I bought the Danio's as cycling fish, yes i know i shouldn't have but i was a complete noob at that time. that was back in January. They all survived the cycling process. and a few months after it was fully cycled They've been slowly dying off one by one. It's...

I'm scratching my head is disbelief as my tank dies off. I have a 55 gallon tank established over a year. I've lost 3 fish in two weeks. The strange part is they show no obvious sign of illness. One by one they float next to the heater for a few days then die. The only sign something is...

Hi all. I have a 12 gallon tank I started in late April. I currently have a cory cat, horsefaced loach and a little guppy. I've had pH problems but thought it was under control. I've had three fish die and the others seem like they're headed that way. It's also weird that I have NO algae...
