Sera Oodinopur with plecs

[Cornuta]

Hi, does anyone know if this treatment has any ill-effects on plecs? I need to dose a tank for velvet which has some altum angels in it and there are some L106s and an L191 in there too

thanks

What are the listed active ingredients in this Sera Oodinopur?
I have always used single component malachite green preparations to treat velvet. It has always worked well for me but often it is also necessary to improve water quality. Velvet tends to attack fish which are or have been kept in overcrowded conditions.
I have raised a large number of Killiefish species and they and especially their fry are prone to contracting velvet. In their case using a teaspoon of salt per gal seems to discourage it's outbreak or speed up recovery when used in conjunction with malachite green. It is relatively rare for plecos to contract velvet but I have had problems with Chilodonella badly infecting recently imported wild plecos. I used malachite green, salt and bare tank to treat them. It takes much longer to effect a cure than simple velvet. The disease does not become apparent until it has reached a fairly advanced stage. It can be difficult to tell the difference between these two diseases at early stage unless you take a skin swab and make slide smear and examine it under a microscope.

I found a pdf with some info - http://www.sera.de/fileadmin/gbi/sera_o ... 01_int.pdf

it mentions that some catfish wont like it.

I'll need to try and source pure malachite green, I normally use salt too for velvet. The angels are newly imported and the plecs were in there to eat any leftover foods

thanks for reply!

So I see it is a copper based medication.
Personally, I will not use any medication containing copper and formalin.
These are stressful chemicals which can strain an already weak fish beyond it's tolerance.
This is my opinion and others may not share my reservations.
I use malachite green at the recommended dose on plecos and most other fish however it is often best to begin with half the recommended dose when treating any scaleless fish.
Some Tetras are said to be sensitive, too although I have always used it on them without any problems as long as I don't exceed the recommended dose. Malachite Green solutions are effective on all protozoan skin parasites like Ich, Velvet and Chilodonella.
Good luck finding some medication. Many States, like California and different Countries, restrict the sale of many of the chemicals used to treat fish diseases because they have been shown to have the potential to cause teratogenetic problems or potential to cause cancer.
