I have completed the fish but am not sure how I get all the different color pond weed. I cant grow all the mushrooms for each individual one. Could someone please clarify or is there somewhere it is posted that I am missing?
Thank you!!

If you use the Rainbow pot that you get at the end of doing the fish, the mushroom planted is RFH immediately and you can place the appropriate color rock for the weeds as you go, don't dust them until you have then all filled. Why do you need to plant multiple pondweeds if you already finished the fish challenge?  You need to do that for the fish but it's the coral for the bottom dwellers that are in the multiples, not the weed.

A way to make it easier to spot enough without wasting time or worrying about a weed going RFH too soon is to attract enough sea myths ahead of time until one or two short of the number needed then do the weed setup later.

The pondweed combos require all the different coloured pondweed at some stage.

I agree, the best way is to use the rainbow pot so your mushrooms are RFH straight away and then attract enough of each Myth so you only need one more to fill the rocks. Then one by one put out your coloured rocks and attract the last Myth, but don't dust the weeds until all the rocks are filled.

I missed that she hadn't done the combos yet.  I need to go to bed.

I have this copied on my back wall:

To do all Pondweed Combos with one set of weeds!

Get ALL your u/w myths to within 1 or 2 of planting the pond weed,
then plant as follow: violet, indigo, blue, green, yellow and orange.

Plant a new toadstool and then a supershroom.

1. Dust for goldfish - orange and yellow
2. Dust for angel fish and squid- blue and indigo
3. Dust the violet for the dolphin.
4. Dust the green for Nessie.
5. Pull the indigo and plant red for the turtle.
6. Pull the orange for the puffer.

It worked fine for me, except I forgot to wait for the squid and had to that one after. Good luck!! ^_^
