Tank Decoration

[LardyDad]

Hello TFF,
can I use slate from the garden as decoration in a tropical fish tank as long as it is well washed beforehand

Yes, usually slate is no problem at all I believe. No harm is subjecting it to the "vinegar fizz" test (see if some drops of any kind of vinegar will cause fizzing) in case there were somehow some limestone streaked in there or something, but that's probably impossible or very unlikely. Also, with rocks like slate you should think about the common sense question of whether there are any sharp edges that might cut the fish.. and of course if stacked, be sure it can't collapse and crush fish.
