Aquarium Advice Activist
I'm not sure whats going on here but im losing a fish every week now. Water parameters are fine. Everything is ok in the health of my aquarium. I lost my guaramis last night. Overnight he became skinny and thin with no visible signs of sickness. I hope there is nothing in my tank that would not show up on water tests. Is there a general type of medication that i can put in even if other fish aren't sick? Just kinda like a clear up medication just in case something is in my tank. Problem is the cartridge to my mini biowheel has carbon in it and you can open them up to get it out. I know carbon will remove meds. Also, do quarantine tanks have to be set up and cycled, heater, filter, etc, and when you quarantine do you take water from the tank you took the fish out of or do you put in fresh dechlorinated water? This is a FW tank with 3 red minor tetra's, 2 danios(used to be 4), 3 rasbora's(used to be 4), 2 oto's(used to be 3), did have a guaramis, and I have one betta. I alternate food between aquarian flakes, blood worms, betta pellets(which the other fish love), and hikari micro pellets. They seem to love the variations! Anyone with suggestions or ideas please leave them. I don't do water changes till my nitrates are above 40 and sometimes that takes 1-2 weeks to get there. I guess the best way to ger rid of any questionable sickness in my tank would be to do a larger than normal water change, like a 50% instead of 25% change. I don't think i did anything wrong. I wash my hands before i do anything in the tank. I have dedicated equipment that i only use for the tank. I'm thinking just maybe unhealthy fish is what it was but something had to make them unhealthy.
