Hello Cecelia
The list of salt tolerant plants is quite limited -
Ruppia maritima and Najas marinumare the most tolerant, with Val. gigantea,
Potamogeton pectinatus, Najas tenuifolia and Nymphaea gigantea showing some
tolerance also. Java fern (Microsorium pteropus is also recommended often for
slightly brackish tanks.
Remember plants mostly like fairly constsnt conditions while
fish are more adaptable so once your plants have got used to a situation try to
maintain the conditions for them. Even if they will tolerate some degree of
brackish they will usually do better in more optimum conditions and you still
need to consider their other needs such as adequate light intensity and
duration, nutrients and CO2 where appropriate.
As far as names are concerned all we can do is tell the
shopkeeper that you won't buy any fish that hasn't also got the proper
identification and consider asking your local aquarium fish clubs to make this
official club policy and write to them and inform them. As long as they
can get away with being lazy and slipshod they will do it. Also many pet shops
are woefully underinformed about fish in general as the owners are often
businessmen and not aquarists.
When you buy garden seeds or seedlings even if the colour is
important for landscaping purposes you still expect to have the identity on the
goods, otherwise how do you know how big it will get, and what conditions it
needs.
In my opinion dark gravel and backgrounds and some p[lants
help your rainbows look good but lights that alter colour should be avoided -
the lights should be over the front of the tank and tilted slightly backwards to
enhance the reflectivity of the scales of the fish. You try looking at the
dofference from simply sliding the light backwards and forwards.

Hi everybody!
I have some questions: (as usual :)
).
1. Which of the plants on the list of
Australian plants likes brackish water and do someone know of other plants
that likes it?
2. What kind of lightning do you use for
your rainbows? I have problems finding a good one that highlights the
colour.
3. Why can't the people that sell rainbows
to the shops learn to put the right name on the fish???
I have talked to a lot of shops here in
Sweden and they only sell red, blue and yellow rainbows. Often do they sell
different spices under the same name! The red rainbow can be both G. incisus
and M. herbertaxelrodi. The last one can also be sold as yellow
rainbow.
Mvh,
Cecilia
The only fishes they sell under the correct
name is the Boesemani.
