Thank you I wholeheartedly agree.

Good question.

I do water changes with 100% RO/DO filtered water which has 0ppm total dissolved solids (the measure of any minerals that are in the water, not very helpful in pinpointing what those minerals are but let's you know what your dealing with at least). So the tank normally has a TDS reading of ~100ppm (last night after a fresh WC it was 84ppm so close enough) which I believe makes i(the water) more susceptible to manipulating the parameters with different methods (could be completely wrong but it sounds right to me). The substrate is about a 65%/35% mix of old ADA AS Ammazonia that I had in another tank and inert natural looking (as much as it can be...) aquarium gravel the respective amounts. So im not sure if the AS is helping at all but maybe a little bit. I also put 3-4 IAL (Indian almond leaves) in the tank a month. These release tannins which stain the water tea color and also I have read that they have an antiseptic quality as well so perhaps they are one of the reasons I have pretty descent sized spawns as the eggs are less likely to mold over. The tank is also loaded up pretty good with DW and they provide water acidifying tannins as well, plus its a must with these Starlights as it is something that they like to lounge/rasp/munch on in their natural habitat too.

That's about it. No chemicals or anything like that. About 6-8 months ago someone was selling Alder cones in the SNS and after doing some reading on them I found the they are supposed to have similar qualities as the IAL. I got a bunch of them too but it just seemed like they did too little for the amount I had to put in the tank plus they wee messy when they broke down and some of them got moldy after a month or so in the tank.

Again I rally have no idea what the true pH of the water is because first off I was using a not the most accurate API test kit and the coloration of the test was a fair amount below the 6 that the card goes down too. The tannins in the water could also have effected the color of the test as well. I may just have to get a decent pH pen or a LaMotte pH kit. But since everything is going well im not too worried about it.

150EH This has nothing to do with your thread other than it's about a Pleco, we had a club meeting and auction at "That Fish Place That Pet Place" yesterday and it is a really big LFS with just about everything you could want. Anyway at the auction someone brought in their Pleco and I have no idea what L# but it was beautiful brown with a zigzag Zebra type striping and it was over 12" long. The auctioneer was afraid to pick it up so the owner came up and held it his hand for the audience to see and I don't think he could touch his fingers together if he wanted to, this thing was fat and calm. Well you could hear crickets chirping and nobody wanted this fish because of the tank requirements I'm guessing, so the auctioneer told everyone it was an orphan and it needed a home so some one bid $5 and walked out the door with it and a 50 gallon Rubbermaid container that was worth $20.

It's just another safeguard. With the pH being so low, the temp so high and these being pretty o2 hungry fish it just makes me feel better having all the protection I can get. And also with Nitrates fluctuating from the amounts of food that I feed them you never know when you are going to get a bacteria bloom and because of that an o2 shortage for the starlights.

I always come back to Tom Barrs experience with L046 Zebras where a whole group of 8-10 that he had expired because there was just not enough o2 in the water due, again to the higher temps they require.

And as for the O2, you should be fine. But injecting O2 will raise your ph a bit the same way co2 will lower it. Shouldn't actually affect anything though
That was my main reason for posting the Q about putting extra O2 in the water. I just wanted to make sure that it couldn't cause any unwanted/unexpected swings in pH.

bsmith Does anyone think that this much aeration will/can cause any issues?




Its a Hagen Mini Elite power filter I have bee using in an adjacent tank and I thought that this would ensure that there was plant of o2 in the water. Haven't had any issues (I also ant find any info pertaining specific pH values and o2 levels of if pH has any effect on o2 levels like temp at all) but since the temp is on the higher side I figured that any extra o2 I could get in the water would be a good thing.

Let me know.

S&KGray Nice pics, very cool indeed!!!

bsmith It looks like this tank of fish produce a spawn about every 25 days or so. I went down to the basement tonight to finish some housekeeping/filter maintenance/substrate rejuvenation (replacing fert tabs in the substrate that spent) and after looking closely I saw these guys and actually made a pretty big find!




I think they are very pretty fry!



Still have the yolk sacks so I would guesstimate that these are a bit under a week old.




Here is where my find is posted. I first thought that this was a different males cave (not the oldest/larges male in the tank). This had me questioning how they selected breeding partners since in nature usually the oldest (within reason, obviously there is a time where the oldest becomes frail or not strong enough to fend off the new young buck on the block) is the most dominant and also the largest so it stands to reason that he would always be the mate of choice. But after going over pleco placement im pretty confident that this is actually the females cave so no revelations just yet! I still have never seen the fry still hanging out in the cave with the parent/s before so it is pretty cool IMO to have caught these pics!

bsmith Thanks HD. Yes, the L183 Starlight is a very difficult Ancistrus to breed as they are from pristine blackwater regions of the Amazon that are super clear but are stained like tea due to all of the decaying organic matter in the water that has fallen from the flora surrounding it. The PH the come from is in the low 5's to perhaps even the high 4's/ Right now the PH in the tank here is lower then the API kit I have which the card goes down to 6. There is also very little TDS in the water too.

HD Blazingwolf nice fry!!!!! i've heard pleco breeding can be quite a challenge!! i've thought of doing it before but it never made it past go.
