rhino, you might want to invest in a quarantine tank. If you had one you wouldn't have had to needlessly kill off the survivors =/

banded loach. Made my zipper loach look like it lost a bar fight there were so many wounds. Lived for 5 days after and died. Gave away that banded loach.

Very interesting thread!

Even though q might be a good idea, it may still not help. I had quarantined 2 Yellow skirts I wanted to add to my existing school, and all was ok and after seven days I introduced them to my tank. I have to say that a blue tetra had gone missing and I had falsly assumed I had flushed him away during a water change.

Anyway, I was gone for a business trip and when I came back the whole tank was infestated with ich and the paramaters were out of the roofs. At the end three Skirts, 2 blue tetras died... and one cory barely survived. The ich had been introduced but may have no broken out if there were not the stress of the bad water. I found the culprit later: the dead blue tetra.

My worst buy... the Skirt tetras, two black and two yellow were my freshwater starter fish. Now wiser and more gallons I have them still and added 2 other in the hopes they would school eventually, but they just don't. Before they had divided the tank by four, now they are sharing it by six.

They make my tank look and be full... geez! But I won't toss them out either...

That's what I'm saying: They were in my 20gal quarantine tank! I didn't dare move them to the 180. So I iced them rather tham risk introducing them to the 180. I was worried the survivors might be carriers of whatever killed the other 24 fish.

Red Tailed Black Shark and 2 Albino Rainbow Sharks! Grrr

Got told the Albinos do better in groups.... Later i found out this is only when there young!

So now ive got a really agressive RTBS that attacks everything and 2 Albinos that fight each other Hate it

I have really hard water here, and I bought several gold German rams online (read..expensive due to shipping) thinking how pretty they were. I acclimated them slowly, with the drip method over 10 hours, and only lost one in the first 2 days. The others seemed to be doing fine, but gradually, one at a time, they would fade, and stop eating, and die. I tested frantically, trying to figure out what was killing them, but it was just the hardness of the water. I've researched the needs of my fish more carefully since then. My Firemouth Meekis are doing great!

au contraire...

COSTIA are evil buggers that will survive a LOT. There's also a Koi virus that will survive a lot and is ripping through koi shows out of Japan.

MY WORST PURCHASE: I'm conflicted about this, but I have to say my fancy goldfish. I love them because they have personalities and they're fat and cute and waddle in the water, but I hate them because they're messy, HUNGRY, fast-growing, and eaters of plants. I can't keep the nitrates below 30 for very long even though I have a 55 gallon with only 5 goldies. There are 2 huge biowheel filters (rated at 100 gallons each) and a large powerhead in the tank. I hate that they take up so much real estate and that if I don't feed them 3 times a day, they start to tear apart my crypts. It's a love-hate relationship.

I have to passionately agree, but to add: switching the ph from 7 to half-way to 8 is still a huge leap, and little fish, especially tetras, are pretty sensitive to that.


Also, 50% water changes may be good for plants, but not for fish, especially new ones that are being stressed from ph, bioload, etc.

Dwarf gouramis. They would dig up my HC and rotala for their nests, I finally got tired of destroying their nests and replanting and got rid of them.

My Dwarf neon blue is a bully. I got permission to put him in the tank at work. My wife was thrilled (as he eats the Angelfish fry) my son said NO. So there he sits: in HIS 180 terrorizing the Angels.
