Vermiculite and digging clown loachs
I am about to start up a new 25 high tank and would like some guidance
in relation to the following. Having followed the discussions on
substrate for some time I am thoroughly confused.
1. I plan to put in some form of 2-3" vermiculite substrate covered with
1" of gravel.
I have 4 clown loaches and lots of bristlenose catfish. Will these fish
dig up the vermiculite substrate either damaging the substrate or
themselves? In my current tank the loaches do a whole lot of digging.
Also, will the use of vermiculite adversely affect the fish in any way,
- the loachs, which appear to be rather sensitive; or
- the breeding behaviour of my bristlenoses.
Also, I have not fully figured out what type of soil/ sand to mix with
the vermiculite - any suggestions welcome. At this stage I am
considering river sand or a purely mineral based cactus mix.
2. I intend to start using PMDD. Having subsribed to the APD for some
time, I have only heard good things about PMDD. Are there any adverse
PMDD effects on fish, in particular clown loaches?
Any comments appreciated.
