New Anubias Heterophylla Melting

[N0body Of The Goat]

My local MA were doing 4 plants for £14, so I jumped at the chance of trying some taller Anubias, they are ~20cm tall with maximum of ~10cm long leaves. They were put in the tank Friday afternoon and yesterday they got a strict 6 hours of the Rio240's 108W T5HO lighting, still the same tubes that came with tank in summer 2010, but they basically have not been used since this time last year when my original array of plants had all perished bar two Anubias barteri nana on bogwood (because I learnt that I was giving them too long a light period with not enough ferts or carbon).

Just before turning the T5s on for their six hours today (more the the benefit of the "onion plant" bought at the same time, think it is Crinum thaianum), I noticed that the tip of at least one leaf per Anubias plant has either gone dark green or faded to a faint brown with a melted/dead look. Besides one plants having a single dark patched leaf, these were healthy looking plants in the store.

No ferts (Prolito) or Easycarbo has been added to the tank, besides putting 1/4 of a Dennerle E15 tablet in the pot holding the onion plant (which I trimmed the roots, peeled the outer layer off and only covered the bottom 1/3 of the bulb)

Is this a normal "sulk" by the plant after a change, from which it will naturally recover, or is there something you think I need to actively do?

I recently purchased some anubias and had the same problem. It now has new shoots coming up after about three weeks, so I would say its normal.

It was probably grown emersed and will go through a change to submersed, happens a lot with aquatic plants I'm affraid. I thought I killed my first ever lot of plants about 3 years back and threw them all out and it turns out they were doing the same thing.

I won't panick yet then, thanks! I'm determined not to kill my second attempt at real plants, half the reason why I wanted Anubias, but also to have avague biotope for some my fish.

I think its something to due with the change in the water. I am in the East Mids and I bought some off a guy down South and it melted back a bit, now its picking up.Last week I bought some locally and its fine.

Water chemistry could be a factor, Fair Oak MA do have one side of a tank aisle labelled as RO, never even thought to ask them if the Tropica plants were in RO too.

Probably a silly question, but at what point should I remove any of these leaves with discoloured tips? My better half has received a new camera today, so I can take a few snaps and upload if this will help you plants gurus to give advice
