Thanks for the info.

This seems like a good place to ask instead of starting a new thread. Are C. reticulatus and C. sterbai able or likely to cross breed, or could I keep them together safely?

Looks like an albino , commonly sold as the "Chocolate Pleco" or "Albino Chocolate Pleco".

Pur faucet filters use carbon cartridges, so TDS, GH, and KH should not be significantly effected.

Sorry for a stupid question : What exactly is meand by type locality than? I know there are several species (keeping 4 different ones myself) but just don't understand Trinidad being mentioned. Cheers Aad

The type locality is where the original specimen(s) on which the species description is ...

Now that I know the problem I can fix it, just hate to see my fish pay the price for my mistaken assumption that my RO unit would deal with chloramine.

it is reconstituted with RO Right and Discus Essentials mineral supplements.

I forgot about this - yes the RO Right alone should be enough. I would be doubtful of internal parasites too, just a thought.

@Bas Pels - TonyC is just doing water changes with the "new" RO water, not completely ...

I don't know for sure, but I think the self-poisoning theory doesn't hold true in a larger amount of water. I thought that only had negative effects when the fish were in a small amount of water (like a bag). The toxins dissipate to non-harmful levels in more water - I think.

Do the other 7 seem ...

Just to have thought of everything - how long was the water treated with oxygen?

All RO systems remove all oxygen from the water, and therefore RO water needs some 24 hours with air bubbling through it in order to get the oxygen dissolved and make the water usable for fish.

I think you normally ...

Something similar happened to a friend of mine in our local club. We never really figured out the cause.

Some theorized that it was due to "self-poisoning", which Corydoras in general and Sterbai in particular exhibit, but ...

A quick question but why are you changing the water so much? I'm not familiar with RO myself, for my sterbais I do a 30% WC with regular treated (prime) tap water on a 60G with around 40 sterbai (juvies to adults) tank is at 78F (room temp) and mine are flourishing.

Just habit from keeping discus ...

Had an odd occurrence last night and I'm not sure what may have caused it. After water changes last night my sterbai became lethargic and I lost 3 of the 10 during the night. Water parameters are good, pH 6.5, NH3 and NO2 are zero and NH3 is nearly undetectable. My water source is RO treated with RO ...

Taking a shot in the dark here, maybe an iridescent shark ? If so then I would trade it back ASAP, they are a very common fish that is not at all suitable for the home aquarium.

I have a pictus catfish, and 3 Neon tetras. Temp 80 degrees F, got them 3 days ago, in a 10 gallon tank and i know they can live in that. (tank was sitting with filter for like 2 weeks) before adding stuff.. Neons run around and play i have not seen them eat but i am sure they do because they are ...

Thanks for the advice, yeah the slabs where what was with it, I've re arranged them to how neighbour had them (as they were just flat) to make a hide at one end then there's little "tunnel" and "cliff" type bits behind a through the others. I know what you mean by the sand my only issue is how can ...

I only wish my neighbour had used neutral/natural coloured stones, don't know about you guys but I do like natural looking tanks? What sort of things have you got in your? I will be getting another plant or 2 I think? X

I would replace the gravel with sand, goldfish love to dig and sift through ...

I would also favour C. trilineatus but without origin it is difficult to be absolutely sure.
Only the specimen in the second last picture looks a bit weird.

I'm assuming they are farmed fish, my LFS doesn't usually deal in wild caught corys.

Is the pectoral fin spine really kind of orange ...

I know none are true julii, just wasn't sure if the last two were trilineatus or "contaminant" species since their patterns are so different from the rest.

I cleared out the "julii" tank at my LFS today and wanted to confirm the ID, are they all trilineatus? A couple have odd patterns to them and I wasn't sure if that was within the normal range of variability for the species or if something else hitched a ride with them.

They won't, quartz and amethyst (a type of quartz) are made up of inert SiO2, the same mineral that makes up pool filter sand.

Very nice, you should see a big difference in the size and health of your goldfish compared to the ones you had in bowls before.

Cycling water is a common misconception, in a mature tank it is actually the substrate, decorations, tank walls, and of course the filter which host nitrifying bacteria ...

Stunning pictures, just added another species to my wishlist.

Yesterday I "rescued" 2 goldfish from the hook-a-duck at the fair.(I try to get as many as I can afford whenever I see them there. I have a proper tank, around 20lts I think, I managed to get a water plant from a neighbour he called it an apple plant or something, I've had to use gravel from ...

I order some fish and they arrived yesterday, set them up in a 12G with sand substrate, live plants, 30G sponge filter and 4" air bar. The fish were wild caught from Brazil, 20 eques (which I believe to be melantonaenia now), 10 Arcuatus, all are juveniles to almost adults. The tank was cycled with ...
