Plants from local streams


PENEJANE

Recommended Posts

Is it possible to get plants from local streams and put them into the tank? I have heard that there is some that are dangerous to put into the tank as they release bad things which will kill the fish. Can anyone show images of some sort as to which ones are ok to put into a tropical tank?

I got a 3ft coming at some stage and I don't want to pay a fortune to plant it out if possible.

Keeping in mind that I am in southland and the streams are currently VERY cold lol

Cheers for any info

I don't see a problem - snails are probably the worst you will encounter. Best if the plants are collected from a spring fed (clean) stream or similar. If worried treat the plants with Potassium Permanganate (from the chemist) or a weak solution of bleach then avoid introducing any fish for a week or so.

Apart from the "weeds" like Elodea, Hornwort etc don't be surprised if the plants die off slightly before producing new leaves and shoots. You have taken them from an environment they are used to and introduced them to alien parameters. They may take a while to acclimitise.

If you plan on having a tropical tank take a look at:

http://www.thekrib.com/Plants/Plants/NZ/ to find what plants are suitable. Increase the tempature slowly (over a few weeks) so not to shock the plants.

For general identification you can't beat the Niwa site:

Happy hunting!

I have hauled plants out of the local waterways too. Make sure the surrounding banks have not been recently sprayed with herbicide or anything else toxic.

Wash the plants well when you get them home and perhaps a quick swish in a weak bleach solution wouldn't be a bad idea either. I must admit I have never bothered doing that myself. My plants were taken from a fast flowing stream so I didn't worry about pests growing in stagnant water.

Penjane, as it's winter you can't just throw them in a tropical tank they will melt / die, warming them up slowly at this time of year is the only way to go sorry.

I would take Shilo's advice too and clean the plants.

1 bug you DON'T what is hydra, it can be a real pain to have in your tanks or thou gourami love them. :D

cool. Thanks for that caserole. What sort of formula for the weak bleach solution would you suggest? I don't want to make my plants white! hahaha

Would christmas time be a better time to get plants? I doubt that it would matter as being in southland the waters are always going to be freezing cold! lol

Elodea and Hornwort are both Pest Plants and it is illegal to keep them or collect them. If you have them, they should be destroyed by burning them. If you get caught with them you could be fined or face prison.

If you are going to collect and use plants from local waterways, be sure you have identified them before moving them. Take only plants that are not on the Pest Plant list.

Glossostigma is a great NZ Native that adapts very well to tropical temperatures. I have it growing very well in my tank...
