Atitagain Posted September 8, 2021 Share Posted September 8, 2021 Doing research on rummynose tetra to try and breed, came across an article (may have been a video, looked and watched so many past couple days) that stated if they live in high PH and high hardness it could make them infertile. I know they come from soft water and I’ll need to get the right conditions to have them breed but this is the first time I came across this. Does anyone know more about this? I ask because I’m already planning on raising fry in soft water, should I keep the parents in soft water if I have success with them to breed again? Would rather not run 2 soft water tanks unless its necessary? Here’s normal conditions in almost all my tanks and the ones that are different are not close to being considered soft.hardness=300+ Buffer=220 PH= 8.1 Link to comment Share on other sites More sharing options...
Fish Folk Posted September 8, 2021 Share Posted September 8, 2021 My opinion … you really want to pursue TONS of botanicals. You want this: I recommend thoroughly studying EVERYTHING you can learn here. Especially searching for precise things archived here. 1 Link to comment Share on other sites More sharing options...
ARMYVET Posted September 8, 2021 Share Posted September 8, 2021 @Fish Folk I know for a fact you would cry if I showed you what I have been dumping down the drain the last few days! I got in a bunch of new drift wood and have been boiling it to sterilize it from unwanted stuff and the water come out so full of tannins you almost cant see thru it. 2 Link to comment Share on other sites More sharing options...
laritheloud Posted September 8, 2021 Share Posted September 8, 2021 I am completely not an expert at this, but my 100% anecdotal experience is that my diamond tetras (which come from softer water) breed prolifically in 10 dgH 10 dkH 8.0 ph water. If you want a higher yield than accidental occasional fry (we doubled our school over the course of 6 months accidentally), I'd follow @Fish Folk's advice and make a tannin soup. 1 Link to comment Share on other sites More sharing options...

That’s good stuff for certain fish! Link to comment Share on other sites More sharing options...
gardenman Posted September 8, 2021 Share Posted September 8, 2021 I've heard that the pH can affect the ability of the sperm to penetrate the egg membrane of some fish. I'm not sure if it applies to Rummynose tetras or not, but I've read that in the past. There's a sperm membrane and an egg membrane that have to be able to fuse and at certain pH ranges they can't fuse. 1 Link to comment Share on other sites More sharing options...

If I do have success or if I don’t with this spawn, I think 🤔I want to start from scratch anyway. Set up a soft water tank buy 10-12 new rummys and raise them in these type of conditions “black water” great info as always 👍 1 Link to comment Share on other sites More sharing options...

I figured this was the case, maybe for optimal conditions, better chances of not having infertile fish, higher yields, ect… Which I’d never be able to create in my fish room. I absolutely want to have success with this project but don’t wanna waste time trying to have scientific study conditions. Link to comment Share on other sites More sharing options...

I think the best way I can approach this for now is “let’s see what happens and give a better more educated go at it next time” 1 Link to comment Share on other sites More sharing options...

I will be jumping down this rabbit hole for sure have read a article and looked through the stock they have. Already have plans for the 60G here I go, at it again! Do you have any of these type of tanks? Pics? 1 Link to comment Share on other sites More sharing options...

Fish Folk Posted September 8, 2021 Share Posted September 8, 2021 We added tannins with these… Firemouths. But not really too much… Link to comment Share on other sites More sharing options...

The firemouths are a good looking fish as well. So you use tannins for water parameters and such not really dark water ? im really liking the dark water look. Something like with a huge school of rummynose and some other creatures as well. I don’t know will research and price it out. Maybe and by maybe I mean, I gotta talk to the wife. I think I maxed out my credit with her.🥴 1 Link to comment Share on other sites More sharing options...

Brandon p Posted September 9, 2021 Share Posted September 9, 2021 I was always told that they needed a soft water and ph under 7 closer to 6.5 with tannis? Link to comment Share on other sites More sharing options...

Yes I think that’s where they need to be to spawn 6.5 even a little lower. My shoal in display tank are really healthy and look really vibrant at a PH of 8.1, I’m just thinking in long term affects to breed the healthiest fry as I can with my set up.

Tihshho Posted September 9, 2021 Share Posted September 9, 2021 You can also use pantyhose full of peat to drop the pH and add tannins. Be careful though, this can drop the water params quick and turn the water dark fast. Plus, if you get a snag in the pantyhose causing a tear it turns into a down right mess. 1 Link to comment Share on other sites More sharing options...
