Hi everyone, I'm very happy to report that the wigglers survived my vacation. I instructed the fish feeding person to feed half a sera plankton tab every other day and installed an additional air driven sponge filter. On a sad note I have to add that the adult male with the damaged tail fin passed a...

Hello everyone, just a quick update: my remaining group of 6 Corydoras hastatus are continuing to spawn. Occasionally I see an egg or two and there are lots of wigglers all over the tank. I placed a pile of ceramic media in a corner of the tank. The adults seemingly do not harm the fry. One male adu...

Hi everyone, about 2-3 weeks ago I bought some wild caught C. hastatus (and 2 other minute fish that were accidentally caught by the LFS). Last night I discovered 5 or 6 Corydoras fry of different sizes. This really surprised me since the parents weren't exactly in excellent condition when I bought ...

Hi everyone, With a H.O.T. Magnum filter. It is hang-on-the-side power filter that can be used with a fluted filter cartridge for polishing water, or with a chamber that you can use whatever media you want ie; zeolite, carbon, etc. Thank you, I 'll see if i can get something similar. I usually mix i...

Hello, Mixing tap water with rain water should provide enough stability to your water. Yes, I assumed that kh 7 would be more than sufficient as a buffer. I know there are some people using pure rainwater for their Corydoras and wondered how they kept their ph stable :eusa-think: I do filter my rain...

Good afternoon, I'm curious: does anybody else use (partial) rainwater for their water changes? If yes: Do you life in an urban or rural area? Do you give any kind of treatment to the rainwater prior to usage? if you use pure rainwater, how do you keep ph stable? I'm using half rain water half tap i...

Hello everyone, I'd probably try to up the water change frequency and add some more plants Thanks Darrel, got myself some Limnobium today. (I had to take out the Ceratophyllum though because it was covered with cyanobacteria.) I have a small UV unit I use in as needed situations. It was purchased to...

Hello everyone, If you can build in negative feedback loops, and avoid single points of failure Could you elaborate on this a bit please? ok, first of all: I really appreciate all the information and opinions you people are giving me! Especially Darrel's explanation about microorganisms and oxygen. ...

Good evening, There aren't really many free living bacteria in the water, they are bound to solid surfaces as biofilms. Ok, I was vaguely aware of that, but I assumed the effect of UVC-filtration as a biocide can only effect bacteria (/Protozoa/algae) in the water. If numbers of bacteria in the wate...

Good evening, I think this quote refers to swampgorilla's UVC-filtered goldfish tank, not his Cory tank: So if you only have one filter that does all your mechanical / chemical / biological filtration, you're probably not gonna want to slow that one down enough to make a UVC effective. You will eith...

Hello everyone, Thanks for the comments! So if you only have one filter that does all your mechanical / chemical / biological filtration, you're probably not gonna want to slow that one down enough to make a UVC effective. You will either have to get another canister filter or a pump that you can sl...

Hello everyone, does anyone have some experience with Corydoras and UVC filtration? Are there any benefits for the fish that can't be acquired with frequent water changes? Here is what my thoughts were so far: To me the concept of UVC filtration sounds very tempting on first thought, especially as a...

Hello,

sounds good, does it require frequent cleaning?
I like your bucephalandra spp., do you use any kind of fertilizer?

Cheers,
Lisa

Hi everyone, From your info given to us it seems that you are very familiar with taking care of corydoras catfish. Actually I am fairly new to corydoras, though not to fish keeping. I made an attempt to keep C. panda a few years ago but wasn't very successful. I surely made some mistakes, predominan...

Hello everyone, thanks for both of your comments, Mol_PMB and adnan! Unfortunately, Hikari fishfood is not easily available in Austria, not even online. But I will definitely put it on my list. Currently I am feeding my Pandas only in the evening six days per week as their tank is fairly new. I did ...

Hello,

wow, that's quite a nice tank! What kind of filter do you use?

Cheers,
Lisa

Hello everyone, I just completed my registration for PlanetCatfish and this is my first post. Since English is not my first language, I hope you will apologize any grammar and spelling errors on my part. My question is whether freshly hatched brineshrimp or mircoworms are good food for (sub)adult Co...
