Re: Nematodes?
I've seen that same impact on the plant, but I doubt it's worm related.
It's environmental, while he may think the conditions are good, I've seen poor condition for a few days do this to ferns. CO2 mainly.
We all have seen java ferns melt back in certain patterns.
We also have fish, shrimps, that would certainly love a treat of worms.
I'm dountful of thios explaination in his tank, perhaps at Tropica, but this is not a large scale hydroponic operation, this is 100% submersed tank.
I've never seen nor found any disease nor parasite(other than fish/snails, crawfish etc) that does this pattern of injury, but I most certainly have seen java ferns melt and lose leaves etc before due to environmental issues.
While that does not rule out that it's not nematodes, it does cast some strong doubts. I need photographic evidence of the beast doing to the damge specifically to java fern and name of the critter that's doing this damage if they are so privy.
If it does attack java fern as they say, they should have some evidence to show for it.
