The first version of the post was deleted due to accidental “backspace” and thus leaving the site. I’ll try to keep it short this time.
1_As to the plants and negligible mineral content:
Me and my friends in Poland are able to grow these plants in RO water without any real problems. They do not grow in an astonishing rate, but survive and insure, that all the negligible mineral content will be replaced into plant matter, removing them from water. Here’s my friends Betta aquarium on pure RO water. No problems with plants so far:
2_As to the Boraras as unwanted neighoburs:
I strongly believe in the survival of the fittest and becouse of that I choose not to breed intensively as I think, that it might pollute the gene pool with treats that would normally be “deleted” by the nature. I strongly believe, that years of intensive breeding without any natural (or stimulated) selection might only result in preserving the form of the Paros but the behaviour. As observed with cichlids in the first captivity bred generations, the breeding mechanisms aare weakening with each generation in captivity.
In my opinion this might lead to crippling next generations of Paros making them unusable if ever were to be reintroduced to wilderness.
3_As to feeding the fry.
If fish are fed with grindal worm, then the fry also shoul be able to eat smaller ones, that were not cought by any other fish becouse of their small size. In the layer of peat they are relatively safe, and when the leafes will be introduced it should become the Paros stronghold. If any of the fry were to wander too far from safety – look up 2_
This post is about four times shorter then the first version, but I think my point is taken. I’d rather have 1-3 Paros fry at a time. that are suited for survival, than lazy captive fish.
