Look them up in the plant section here or plantgeek or tropica.
Bacopa might be too stiff in the stem to go hanging.
I have grown cardamine and Hydrocotyle in terrariums where they are emersed to submersed or submersed to emersed. Have grown Ludwigia arcuata emersed to submersed in a glasshouse.
Plants that will grow emersed and then submersed would include: Cardamine lyrata, Hydrocotyle leucocephala, Heteranthera zosteraefolia,
Ludwigia repens or Ludwigia arcuata (needs strong light)
If they sit upright like red or brown ramshorns they are their babies. If they are the same shape but on their side they are the pain in the but snails which I don't know the name of. Clown loaches love them.
The difference with using a can of flyspray is that you can use it once then ventilate the room if you want to. The automatic ones mean you are breathing insecticide night and day and so is every other living thing in the house.
There is no way I would want to be in a room with some machine automatically spraying insecticide every few minutes. You might as well be a complete idiot and sniff a can of flyspray and end up with a pickled brain.
You are right. You can expect to lose all the submersed growth as the structure of the leaves is quite different. The trick is to have enough emersed growth to support the plant before you keep it completely emersed. You can assist the conversion by keeping them in a bell jar setup so the humidity is very high.
Are they repellents or insecticides. The repellent we used to use was dimp -- dimethyl pthalate which we got cheap as it was used in manufacturing PVC products and was lying around in large drums. Don't know about toxicity to aquatic critters though. The toxicity can be caused by other products such as carrying agents or synergists which may also be present.
The albino frogs that are around are the green and golds that normally are found in Northland. They have been heated to get them to breed in the winter and are therefore out of season and may breed towards the end of summer.
The modern tubes last longer than the old ones and they are generally stuffed when they go dark at the ends. It used to be 1000 hours but now I believe it is way more than that. You can replace them in a staggered way and therefore get into time payments. What K rating are they to be that price?
Guppies have eggs like other fish it is just that they normally hatch before birth. In this case as suggested it has been born early and has not developed to hatching through the stress of being moved. I keep female guppies in a large trap semi permanently to avoid the stress of moving them when heavily gravid.
I haven't tried with java fern but I had anubius in a glass house and sprayed it regularly but it didn't survive. It grows so slow that it probably didn't have enough emersed growth when I put it out there.
I am going to make some up today for myself so can throw in an extra for you to pick up if you want.. PM me and I will give you the address and arrange a time. I sell white worm cultures and give away microworms.
What looks like roots is actually just and anchoring mechanism. The rhizome is the stalky bit that the leaves grow from. You should not bury them in the media as they may rot. thay do best anchored to a rock or driftwood. They feed through the leaves and generally do not need additional fertilizer. The black spots on the underside of the leaves are not a problem and are part of the reproduction cycle. They grow emersed in nature in continuously wet places like near waterfalls.
