Re: Corydoras adolfoi surprise eggs

As a conclusion to this thread, the male was not fertile. I added 10 more "adolfoi" (which turned out to be duplicareus) and they are spawning as well. I have 1 female adolfoi still laying eggs but these all develop fungus every time. The duplicareus eggs do hatch. I'm also quite certain t...

How to keep aquarium cool?

In the Netherlands we have quite a big heat wave at the moment, which we're not used to at all. As a result not many people have air conditioners so our tanks can get quite hot. Today it's going to be 37C (99F). My tank at 9 in the morning was 31C. How to prevent it from heating up further? I am not...

Re: Duplicareus Dying. Roller Coaster Parameters or New (sick) Additions?

I doubt it was the TDS change alone that killed your fish. Duplicareus are not that delicate. Some breeders of l-numbers do quite drastic changes in TDS to get them to spawn. (Lowering it) I don't know what exactly caused it. My guess is old age and maybe shock for the other two after the big water ...

Re: Corydoras adolfoi surprise eggs

A little update, 3 days later none have hatched. This is likely a fertility problem. The eggs in methylene blue have all fungused. However the eggs in catappa extract water are with an exception of two all still good. This is amazing because I think none of the eggs were fertile. I have 3 females an...

Re: Corydoras adolfoi surprise eggs

Day 2. All the eggs seem good. I've never had these eggs hatch before so I'm uncertain if they are fertile.

Re: Prepared aquariums for Corydoras eggs

Looks very professional, so you just put the eggs in there until they hatch? Do you use it as a growout tank too? And do you do any water changes before or after the eggs hatch?

Re: 300L - Can i keep these plecos together?

You probably could, but if you want them to display their natural behavior I would go a little bigger. Right now I have 5 adult L121 in a 80×45×45 and I personally find this too small. I'm thinking of selling two or getting a bigger tank. You would not be severely overstocked or anything though so d...

Re: Anyone keep corydoras pygmaeus in hard alkaline water?

Re: L200 not eating propperly

I would suggest to not be afraid of overfeeding. While I was getting my corydoras in spawning condition I 'overfed' quite a bit. This is when I noticed my l121 getting more active and eating more. Now I feed them much more and they eat much more too. They are even growing slightly even though I had ...

Re: Corydoras adolfoi surprise eggs

I don't get it. Today there are only four eggs left. Somehow the live eggs get fuzzy with a thin layer of fungus and I guess the snails eat them. What could be the cause of this? My guess is either tiny particles in the water (main filter broke, had to install internal filters) or too little water f...
