    Hi guys, I noticed that my bottom fish (mainly botias) and then a few other types of fish, started acting like they itched. You know, the scratching against rocks and wood behaviour. I tested the water..everything good. Looked with magnification glasses at their skin..nothing..

    Finally I noticed that the lead sinkers that I had used to anchor plants looked corrosive. I pulled them all out, did a 75% water change, and the trouble stopped. Is it my imagination?

    the lead strips that you find on plants are generally not lead anymore (not in the UK anyway) as it’s not a very nice metal when in contact with water!

    if they were corroding (rusting) then there is good chance that they were some sort of steel (contrary to popular belief steel does rust depending on the type) so maybe iron poisoning? Although I think that would kill them outright?

    I think it was probably your imagination. Aquarium plant strips have been manufactured as non invasive for quite a few years. I think it’s pretty unlikely they were the problem.

    I think Bluedave is on the right track. I used larger sinkers that fishermen use when sinking hooks/bait. the corrosion was blue-ish color and felt chalkie. the plant strips felt the same way. I think some kind of heavy metal poisoning was going on. In any case, removing the sinkers and doing 75% water change stopped the wierd itching activity of the fish
