Echinodorus problem.

[Phillip Macken]

I added these to my tank about 2-3 weeks back and now they have gone and done this. This happened over the course of about 2-3 days and despite my best efforts I can't get them to come back. The roots have dug in well to the substrate and I have high light and use Easy-Live Easycarbo and other ferts. No Co2 diffuser (Can't afford one at the moment).

Any ideas/Help?

Cheers

Those are the old emersed leaves which will decay, fall off and hopefully be replaced by different shaped submerged leaves.

That said it also looks a bit like mechanical damage - do you have a plec or similar which might be munching on them?

Will it fix itself or will I have to trim them?

I'm with bigtom emersed leaves, you can trim them off as close to the crown as possible to stop them decaying in tank new growth will soon follow.

Either really - I'd probably trim then once you see new leaves coming through but I'm not sure what's optimal.

The leaves won't recover, the plant needs to regrow. Trim most and leave a leaf or two only. If you leave the old melting, the plant may struggle to provide for new leaves. If you cut all of them, the plant can die.

Looks like you got my pleco in your tank lol

Like Tom says - trim damaged leaves off, as soon as you have new leaves visible ( I see new leaves already ).Leaves of Ech. bleheri should not ever decay in this way, though, so I'm pretty sure the problem will continue on the new leaves. Something MUST be eating off softer parts of leaf-plate, to cause this appearance........and Plecostomus is my prime suspect, too ( but very huge sp. of snails can do this too ). You have to find the cause of problem, to be able to solve it. I don't believe this is just a matter of "adaption"-problems for the plant, and therefore it will not likely solve itself !!

I concur, that is rasping damage, tear those leaves off at the base, as soon as there are new leaves, and find the culprit. (you can see the same kinfd of damage on page 8 of my large tank journal)
