channas and wc?

[Lizardking]

i´m doing research on bleheris and there is one thing that I dont really get and that is why its considered a good thing to not do waterchanges?

I get that in the wild they live in slowrunning or still waters, but IMO this has nothing to do with such a small biotope like an aquarium is.

I guess bleheris produce enough waste to mess up the parametres if I dont do wc in a month like some people do.

I want your opinions on waterchanges and channas.

hi mate , the proof is in the fact that channa will not breed with frequent water changes , i agree that if kept in a bare glass aquarium you would have no choice but to do water changes or you would have crazzy perameters , that is why all breeders set there channa up in a bio-tope type setting , i.e. a fully planted low light low tech system , this approach means that the plants consume nitrates and phos as part of there natural cycle , and you will find most of theese setups will have zero nitrates without any waterchanges and will have far more stable and better perameters than someone who keeps channa in an unplanted set-up with lots of changes (even tap water has high nitrates so you could never get zero nitrates doing even daily 90% water changes) as i say the proof it in the fact that the channa breed in theese set-ups , if they breed you can bet they are happy , also can be checked with test kits.
i was only converted myself around a year ago to this methos for channas but have done prior research on the method and it is sound and does work .

my previous breeding set-ups where african cichlids who do far better with heavy changes ,so it was quite hard for me to get my head round , but it does really work . all the other channa i have kept over the years have just been single fish, so this was not as important, they will survive with water changes it is just better for them without and essential for breeding

ps a great number of micros and pleuros are lost after waterchanges esp when young. this is when they really benifit from the planted set-ups also

thanks for your reply!
I guess keeping channas is like taking everything you´ve learned about waterchanges and put it in the garbage and then press delete.

but isn´t the growth rate halted with no wcs?

one other thing: is theres any tips on preventing the channas from jumping out of the tank when I work in it?

you got it first time
channa are not like other fish
forget everything you ever learned and start again if you want to be successful in keeping and breeding

the floating plants stop jumping nearly 90% of the time , use water lettuce or some thing similar

i have just wrote another reply on the forum saying ,tear up the rule book lol , you guessed right

our set-up does not stop growth rate , nitrate in excess stops growth ,this is proven . on the lowtech lowlight set-ups. nitrate is just about at zero all the time , in a conventional set-up nitrares climb to around 50pmm or even higher if your lazy with the set-ups , then when you do a waterchange with new tap water you dilute this back down to around 10ppm and the cycle continues, so as you can see the method we use gives better growth - less nitrare = better growth .

Ok. Thank you very much!
