I agree - plants, fish and the happy-looking penguin all look great.

Been away for the weekend came back to see most of the leaves on the new Nymphae plants shredded. Obviously by the Amano’s and possibly RCS. I’m not too worried at the moment as I can see new shoots appearing. The shrimp will get their normal fill of wafers tonight so I’m hoping they will leave it alone. I think once it’s established it will probably hold its own.

Hope the plants are recovering @daveyng ?

This got me thinking... when you say shredded what do they actually look like? I have Amano but have never associated them with eating my plants... what are the warning signs?

I’ll get a picture of the damage later. I’m wondering if the leaves were starting to ‘melt’ as the plant is presumably grown emersed. If that it the case the Shrimp are only doing their job and eating the dying tissue. I can see some new growth which is promising.

I suspect that you may find that once they latch onto the Nymphoides being edible, the writing may then be on the wall... My lot would oddly leave one, or more, leaf alone for a while, instead preferring to work on a leaf that had already been started upon etc...

Easy to see when they have a go at the Nymphoides because the stalks are long and flexible, so the sheer weight of an Amano on a leaf would bend them over significantly...

I recently added an Alternanthera reinckii Pink to the tank and was (still am) worried that with having similar bendy stalks, it too may come under attack - but nothing so far, thankfully...

I have a backup plan in case the Nymphoides doesn’t make it. I have purchased 1 Aponogeton Henkelianus bulb and will plant that in the space behind the Nymphoides. The leaves on that are hopefully less prone to a full blown “Shrimp Assault”.
I have also got some Echinodorus Tenellus to add in the foreground. I am going to prune back the Crypts at the front left of the tank to allow for this addition.

I will be really quite envious if the Nymphoides does get left alone in the long term and "makes it"... Fantastic looking plants, for sure...

This is really interesting. I don't have shrimp in my tank. I'm sorry (for you guys) to say tbat my nymphoides is looking famtastic. It obviously has thinner, more delicate leaves than any of my other plants. Perhaps that is what makes it attractive to shrimp?

TopCookie · « **Reply #28 on:** June 21, 2018, 10:28:19 PM »

They are such a great looking plant, eh... Gutted that I can't have them now...

daveyng · « **Reply #29 on:** June 21, 2018, 10:30:09 PM »

Definitely the Amano’s eating the Nymphoides. Spotted one chomping at a leaf. Weird thing though, the stems seem to still grow with no leaves. I have a couple of pics to upload tomorrow.

daveyng · « **Reply #30 on:** June 21, 2018, 11:01:22 PM »

Here are the pics of the Nymphoides. Bit blurred I'm afraid. One shows a shrimp (greyish blurred object) eating a leaf.
As you can see there's not much left.

Matt · « **Reply #31 on:** June 21, 2018, 11:07:10 PM »

Thanks! I've never seen this in my tank... yet... it reminds me of what snail do to plants in the garden.

I wondered if anyone can help solve my puzzle. I bought a tissue culture of Nymphoides hydrophylla 'Taiwan'. There was so much that I soread it around one end of my tank. Since then, there has been wildly different growth rates.

In the photo below, it is possible to see the huge plants at the back of the tank and the tiny little leaves on the far left. The latter appears to have not grown at all, nor has it particularly decayed, so must be alive. Any suggestions over which nutrients I need to supplement the tiny plants with the get them to grow?

TopCookie · « **Reply #35 on:** October 09, 2018, 10:29:41 PM »

I wish I could help here... love that plant, but mine became a salad bar for the Amano shrimp very quickly once they realised it was edible...!!!

Mine did grow like mad with not much in the way of added nutrients, but what I was adding was TNC Lite at the time, if I remember rightly... I would have thought most water column fertilisers would do the trick though...

Helen · « **Reply #36 on:** October 09, 2018, 11:15:11 PM »

The filter outlet goes across the back of the tank. Could the plants there strip the water of nutrients so effectively that the plants furthest from the filter don't get anything?

The other thing I have noticed is that there is quite a bit of mulm at the base of the tall plants. It is behind the bogwood, so pretty inaccessible when vacuuming (without damaging the plants). And although there is some visible amongst the gravel around the tiny plants, it doesn't really compare.

It is a pretty plant and I agree about it being fairly delicate. I have noticed some of my fish fighting over leaf shreds. But I think they only eat the leaves that have already started to break down. The leaves seem to disintegrate almost in the same way as the cattapa leaves.

I'm not great with plants, so perhaps this is one for @Matt
It is a lovely looking plant though.

daveyng · « **Reply #38 on:** October 10, 2018, 06:38:01 PM »

Mine ended up as a feast for the Amano’s as well. However, I managed to save a plantlet and put it in the Pond. It’s growing albeit rather slowly.
I pretty much agree with the observation about the larger plants and the nutrient stripping. My Lily grows like wildfire. I am assuming that the surface leaves help it to absorb more CO2 than the fully immersed plants.

Extra mulm will help the plant so no worries there. There is no way the other plants could strip the water of nutrients, else the plant next to it would also be suffering and the nutrients would only be available in the tank for a mayyer of minutes... there is no way this is the case. It is a very fast growing plant so does have a high nutrient demand... but only when it is growing!

The plant may well have been grown in air in the nursery and it is shedding its old leaves to replace them with new growth adapted to underwater life. This is a similar process to the quite widely known crypt melt.

What are your nitrate levels in your water?
