Getting L204s back into conditions

I just got 3 L204 ( Panaqolus albivermis ) but they're definitely semi-starved. (The place I got them doesn't ever feed plecos correctly, and they were supposed to call me when they came in, but they called the wrong number and so the plecos sat in their care for a while.) I have them in a 55 gallon...

Re: About filtration

I have Walstads book on its way in the mail but I have not read it. However I have suspicions that she is attributing too much to the plants and too little to microbes. I have Walstad's book. I thought it was very good. Disclaimer: I also know Diane Walstad (although not well). Disclaimer to the di...

Re: About filtration

It seems like Mankysanke is claiming that the center is more negative (and, obviously, the outside is full of positive ions) which causes the ammonia to "switch partners" constantly, moving inwards each time. This sort of behavior is possible for ionic bonds, which are not bonds between two specifi...

Re: About filtration

Reading "Mankysanke's" explanation it seems reasonable but for one thing and that is that the negative charge of the clay particles constantly draws the positive ammonia toward the center. Why doesn't the ammonia stick to the first negative ion exchange surface it hits? If I am right and "Mankysank...

Re: Krytopterus vitreolus constitution

One interesting thing of note: the fish in the left of the picture has lots of black pigment all throughout its body, on the bone the notochord, the skull, eyes, etc,. It was the last of a batch separate from the others. I'm guessing its a wild caught fish. Opinions? Well, to the best of my knowled...

Re: Are Columbian sharks ok with full saltwater?

Someone said on another forum that they acclimated their fish straight from freshwater to marine the fish were fine in a reef tank for a short while then died, so no I’m stuck, did the salinity kill them or the reef environment. The salinity change, probably. You might be able to survive in very wa...

Re: Creating ideal conditions for L260

If the goal is more oxygen and not actually more current then why not just use airstones? The argument I generally hear against airstones is that very little oxygen actually exits the bubbles into the water. This is probably true. However, the reason powerheads oxygenate water is that they "stir" th...

Re: Need more help with my columbian sharks please

There is no stress or issue with the cycling as there’s no free ammonia thanks to prime and stability my ammonia alert confirms this as does API test kit, eventually the tank will cycle until then the ammonia and nitries are being bound and not toxic. There's always stress in moving fish. Can't be ...

Re: Need more help with my columbian sharks please

UV sanitizer would be an overkill in my humble opinion but many people, especially who own very rare and expensive fish, opt to have one. I have one, but I've only ever used it to try to control a mycobacterium outbreak. I don't leave it running in any tank normally. Let's review the problems: 1) T...

Re: About filtration

I am a huge fan of Mattens. I have 3 tanks which rely primarily on them. Almost as much, I like the Poret foam cubes. This is a brand and I am sure there are other brands as good, I just ended up using this one. I'll second this. I have a whole aquatics lab running off Mattenfilters, and we never h...

Re: What is actually causing the mass death of Corydoras fry during the first few weeks of life?

For marine fish there is some research saying that some fry are actually born too small to eat properly. Your experience with some fry surviving in the waste tank suggests that the mechanism may be genetic - some fry will die, some fry will survive, and if you throw a survivor in the waste tank it w...

Re: How many ottos for a 55Gal tank

I only have planted tanks, but my understanding is that Otocinclus spp. are much more difficult to keep without plants. In terms off the lack of success in growing plants, it is unlikely to be too much light or too long a light period. cheers Darrel I've had good luck with otos in a heavily planted...

Re: 13 spawns in 6 weeks: It doesn't get much better than this

Storms can have fast changes in air pressure - changes fish are able to detect, although I wonder how. After all, the difference between half a ppi, that is some 50 cm water pressure, is something quite a few fish meet without consequence a day just going for a breath. But some do detect such a cha...
