cherry barbs and catappa leaves

I am considering using catappa leaves in my 20 gal tank. At present there are 5 cory cats, several otocinclus and 8 cherry barbs. Would the barbs tolerate the brown water tannins? I think the 2 types of cats will be ok..

thanks,

Gina

I believe you're referring to "ketapang" leaf or Indian almond leaf. I have never seen anyone setting up acidic environment for cherry barbs, cories and ottos before. I have only seen people setting up such environment for neon tetras and various anabantoids. Sometimes I'd rather leave the water parameter alone if everything is doing fine for me currently. I have killed a lot of fishes in the process of trying to use the leaves for my tank last month.

Just curious. What type of fish died and what type of leaves?? (Yes, Catappa and Ketapang are other names for the Indian Almond leaf). I use Indian Almond leaves and I don't find that using a few leaves here and there causes the PH of the tank to swing in a noticeable way.
There was a recent article on the "healing" properties of these leaves (I need to go find out where I had read that) that I read at the same time that I was treating a Discus in QT with a VERY badly injured eye. That fish made a remarkable recovery. I'm sure that the voodoo of the leaves weren't the cause of the recovery but they did not hinder the recovery of my fish. Just my 2 cents.

the healing properties and the strengthening of the immune system is really the reason I want to try them. My understanding is that since corys, for example, come from the Amazon, then their natural environment is more towards this "blackwater" sort of thing. Of course, the majority of my cories were tank raised.. but still.. Since my tank is only 20 gallons, I was only going to use one or 2 small leaves at a time.. replacing them every 1-2 weeks.

I do understand the notion of "if it ain't broke, don't fix it" though.

Regarless, either way I will be getting more live plants, since my nitrates are a smidgen high at 40. My water here has a pH of about 7.6 and the water is very hard. Aside from the continual fight with the gill flukes, they are otherwise doing well. All the fish occasionally flash on my slate rocks, but it's not extremely frequent... was hoping to try the leaves to see if they helped in any way... I am extremely wary of trying any medications since my last attempt almost ended in disaster for 2 of my cories.. The Elegans started to decline very quickly, although the other cories, not elegans, seemed to be fine.

One or two leaves replaced every few weeks will cause no harm to your fish, IMHO. I say go for it.

I got lemon tetras (that had never died for the past 1 year & breeding occasionally) and black phantom tetras killed when using ketapang leaves. I couldn't be sure whether it's pH swing or the leaves were contaminated. I got the leaves from a tree at the roadside. So, it's unknown whether anyone spray insecticide or acid rain inthe city caused the problem. Washing the leaves did not help. Once I removed the leaves, everything's back to normal again. Therefore, I am applying the "if it ain't broke, don't fix it" idea now.

Yikes, I'm sure it was some type of a containiment or pestiide on the leaves, or perhaps these leaves in and of themselves are toxic to fish?? I wish we knew what kind of leaves they were. I'm always so urious about these kinds of things.
The Indian Almond leaves that I purchase are from a seller on Ebay and she has a great product (nice huge leaves) for a great price. I think I pay less than $10 for 50 leaves. Good stuff.

Usually the leaves should be safe to use. My case is an abnormal one

Indian Almond leaf

Can a kind soul give me more info on the IAL? Also, years ago there was quite a bit of stir about using hay to stop algae. Any update on that?

Here are some links about Indian almond leaf:

An alternative to Indian almond leaf is oak leaf but I have never tried oak leaf as it's unavailable in my country.
