To reply to both of your posts together;-
Comets are goldfish - they get just as big & are just as messy. You could
only keep three or, at most, four in a 40g tank ;o(
Goldfish love plants, they eat them so your choice becomes very restricted.
Java fern is probably the most reliable. Egeria (elodea) is a good snack
that may grow quickly enough to remove some nitrates. Be careful as a lot of
the plants sold are not true aquatics & wil slowly die off however well you
look after them.

The Plecs will out grow the tank very soon, the sucking loach could become
aggresive & will grow big. All of these are tropicals so need warmer
temperatures than goldfish thrive at. The weather loach should be fine with
goldies.

Cycle is not AFAIK highly regarded. Try adding a pinch of fish food and
taking a reading next day. Nitite is a good sign -what is quite high?

Being very new to the hobby could someone please tell me the procedure for
adding plants to the aquarium and what to go for.

I have a 40g tank and I am going to keep Goldfish and Comets is there a
plant or plants that they particularly like, I have seen the plants in the
plastic pots which look very good and I don't remember them being around
when I was a youngster with my Goldfish then.

Being a newbie I am into week3 of my cycle, I have been adding cycle
liquid
and from reading other articles in the newsgroups am expecting high
ammonia
readings.

So far ammonia is showing as zero but Nitrite and Nitrate are quite high
is
this possible without some kind of ammonia reading.

Thanks for putting up with my inexperience, but I hope to be up to speed
pretty soon (about 30 years I guess).

Cheers everyone,
