Catappa Leaf

Terminalia catappa is a large tropical tree in the leadwood tree family, Combretaceae, that is native to the tropical regions of Asia, Africa, and Australia. It is known by the common names ketapang (Indonesian), Bengal almond, Singapore almond, ebelebo, Malabar almond, Indian almond, tropical almond, sea almond, beach almond, Talisay tree, umbrella tree, abrofo nkatie (Ghana), tavola (Fiji), castanhola (northeastern Brazil), zanmande (creole) and kotÅl (Marshallese).

Keeping the leaves in an aquarium may lower the pH and heavy metal content of the water. In the shrimp hobby it helps maintain tannins in the water similar to the natural environment for dwarf shrimp and also may inhibit bacterial infections in shrimp and fish. The shrimp will also graze on the leaf for micro organisms and also eat the leaf itself. When you go away for a week or so, it's more than enough food for the shrimp.

The catappa leaves are often sold in varying sizes, with small leave approx. 18-21cm, medium leaves approx. 21-25cm, and larger leaves at approx. 26cm-30cm.

Instructions

· Use 1 Small leaf per 10L of water, 1 Medium leaf per 15L of water, 1 Large leaf per 20L of water.

· Rinse leaf in hot water for a min (no more) and then place directly in your tank, it will sink over time.

· Leave in water permanently, it will eventually vanish as the shrimp eat it.

· Add a new one every so often making sure you always have some in the tank.

Good write up BB, one thing you for got was, the nuts are good to eat and are a bit like Almonds, hence the name and they are very common around here.

Great write up BB does it stain the water? I've just used purigen to clear tannins out of a tank? Also is the umbrella tree we have here in Australia ok? I keep picking them up after they blow in from next door and throwing them out if they are the same whoopee I can get plenty

Awesome write up, as usual, BB! :victorious: Another thing which needs to be mentioned is that you can only use leaves that have fallen off the tree naturally, the sap left in green leaves is not good for aquarium use :encouragement:

yeah i added some about a week ago maybe more but it finally got soft enough for them to pick at it and it looks like they enjoy it :)

      Alright, I've done a bit more research on gentian violet's cancer-causing potential but I haven't yet done research on malachite green's to compare. But from reading the California propositon 65 document about GV (North Americans incl. some Canadians will recognize this as the law that causes some products they buy to be labelled with "known to the state of California to cause cancer", including the exact product I bought) it seems that the risk of cancer is related to internal use, either injection or ingestion. Speaking of ingestion, I think GV bans mainly relate to its use in treating fish/shrimp/etc. which are intended for human consumption, because of the above. And in countries where GV isn't banned for this purpose, it does seem to get used on various species of shrimp without causing any issue for the shrimp themselves (at least enough so for shrimp farming purposes). See the following: In February, the FDA Began Rejecting Imported Shrimp for Gentian Violet and Chloramphenicol (2022 article by Southern Shrimp Alliance) FDA Starts New Calendar Year by Refusing Antibiotic-Contaminated Shrimp from Three BAP-Certified Indian Processors and Adding a BAP-Certified Vietnamese Processor to Import Alert (2024 article by Southern Shrimp Alliance) Southern Shrimp Alliance and some other organizations have tons of other articles in this vein, but I'd be here for a while and would end up writing an absolutely massive post if I were to link every instance I found of articles mentioning shrimp shipments with gentian violet and/or leucogentian violet registering as contaminants. That being said, I know shrimp farmed for consumption and dwarf shrimp are often somewhat distantly related (in fact, the one time a shrimp's species name is listed that I can see, it's the prawn sp. Macrobrachium rosenbergii, who at best occupies the same infraorder as Neocaridina davidi but nothing nearer), but this at least gives a slightly better way of guessing whether it will be safe for aquarium dwarf shrimp or not than my bladder snail anecdote from the OP.

      I would hazard a guess that perhaps those eggs were unfertilized and thereby unviable? Did the eggs change colour, usually yellow to grey as the yolks used up, or any eyes in the eggs. Is your water ok, using RO remineralised and the parameters in range, as I have heard others say that if the water isn't good it can 'force' a molt? How is it going overall, do you have a good size colony in the tank, you may have reached 'maximum occupancy' as a tank can only support so many occupants.

      Hello folks,  The current problem I am having is that my Taiwan bee shrimp are molting before all their eggs have hatched.  Often the shrimp keep the eggs for 40+ days.  During that time, they lose about half or so, either due to dropping or duds or whatever.  Shortly before molting they look to have about a dozen left, and then they molt with about half a dozen eggs still on the shell.  Then the other shirmp will come and eat the shell.  These last few times, I have been getting around 0-3 surviving babies per batch.  I figure I can make the eggs hatch faster by raising the water temperature more (currently around 68F, which is already a few degrees higher than I used to keep it) or make the shrimp grow slower by feeding them less (protein).  Currently I feed Shrimp King complete every other day, and also a small dab of Shrimp Fit alternating days.  Maybe I can start alternating with more vegetable food like mulberry?  or just decrease the amount of food?

      Yeah, cancer risk was a thing I'd seen mentioned a lot when looking into gentian violet briefly. I kinda just figured it might only be as bad as the cancer risk of malachite green as well, but maybe I should look into it more. I've been doing a pretty good job of not getting it on my skin and also avoiding dunking my unprotected hands into the tank water while treating my fish at least, though. Maybe I'll just not use it once I'm done this course of medication anyways, because I know a store I can sometimes get to that's pretty distant carries both malachite green and methylene blue, and in pretty large quantities.

      Can't help you with Gentian Violet, sorry. It is banned in Australia violet for potential toxicity, and even possible cancer risks. I thought it was banned in Canada as well. At least, you now know why there isn't much info on gentian violet medication and it's use. But keep an eye on the snails after a week. If it affects the snails, it might not kill them immediately. So keep checking for up to a week. Much safer options out there. No point risking your own life over unsafe products.
