this is great information. I’ve been out of the hobby for over 10 years and a lot has changed since then.
I picked up a 20gal tall from PetCo yesterday as all of their tanks were 50% off and $24 for a brand new QT tank seemed like a great deal.
I’ve always liked to paint the back black and the bottom white for my QTs. I feel a black back combined with a large PVC T provides a place for the fish to “hide” and help them with the healing process. I like the white bottom because it helps show where leftover food or poop needs to be vacuumed out and also helps me observe the fish.
1: I have a small powerhead in there currently. Should I remove it?
2: In your current steps you mention to acclimate the fish but didn’t elaborate. I went to the sticky with the links and the first link has acclimation steps, but the QT steps are different from your latest post here. So I’m kind of confused. Obviously I want to follow the latest guidelines in this thread. However what is the best way to acclimate a fish just brought home from the store prior to adding to the QT? I used to drip acclimate. Is that still the best practice?
I believe Jay is out of pocket for a day or two.
With regard to the powerhead, you should be fine as long as it doesn't overpower the particular species you have in QT and if you have some type of structure where the fish can hide if they don't like it.
With regard to acclimation, drip acclimation still works well. However, if you buy a fish on-line, the ammonia levels may spike before you can complete, particularly if deliver is delayed for more than 24 hours. In that case you will want to aerate the water, measure for ammonia if you have an accurate test kit, and possibly acclimate more quickly. Jay also cautions about increasing the salinity too quickly for both fish purchased on-line and from the LFS. Below are a couple of quotes from a recent thread where Jay discussed this issue.
Do you know the specific gravity/salinity of the dealer's tank compared to yours? I see a lot of acclimation issues when dealers hold there fish at 1.020 and then folks try to acclimate them to full salinity at home - that causes fish to dehydrate, and smaller, thinner fish (like Biota tangs) have more of an issue with this.
Yea the salinity was at 1.02 and i had brought him up to 1.025 over the course of an hour or so maybe, he was in 1.025 for about 48 hours before he died, He was very small.
No luck with the fish store on that front... thanks for the reply
Sorry - that is likely too large of a rise for a small YT to go through in an hour. One trick is to drop the salinity of the destination tank to 1.020, then acclimate the new fish over, then gradually bring up the salinity of that tank up over 2 days or so. For small fish, I try not to raise the specific gravity more than 1.003 units in 24 hours. Oddly, you can drop the specific gravity much faster, the fish tolerate that just fine.
Appreciate that, ill be much more careful about that in the future thats for sure.
