Re: London Plane: is it aquarium safe?

Hi all, Good to know! We just had a London Plane tree planted in front of our house last fall. I’ve been meaning to experiment with the bark. I've never been to the United States but from the little bit of research I did yesterday it seems that even with you London Plane is planted much more widely ...

Re: London Plane: is it aquarium safe?

Hi all, @bekateen the wood is fine to use. You may find that some of it already has a central cavity, I have bits in some of my tanks. Do you have Black Locust Trees ( Robinia pseudoacacia ) on campus as well? That is another good one. I haven't tried Plane leaves again recently, I have easy access ...

Re: How many ottos for a 55Gal tank

Hi all, So does a quarantine tank for ottos also need to be heavily planted? Could it just be filled with floating plants like guppy grass, cabomba, etc I would have plants, they like broad leaves to rest on so a potted Amazon Sword ( Echinodorus bleheri ) would help.@Apistomaster used this approach...

Re: How many ottos for a 55Gal tank

Hi all,
Thats it, what @Bas Pels (and @Lycosid) say.

I'd definitely have "Structural leaf litter" as well as plants. Have a look at <"Natural habitat..... ">.

Re: How many ottos for a 55Gal tank

Hi all, Right now very few it has been reticulary difficult for me to keep plants alive in this tank. I have tried elodeas, anubias, java ferns, java moss. The only one that last for some time is the java moss. I was thinking of adding some duckweed. I only keep the lights on 6 hours but maybe there...

Re: Top Ten Corydoras

Hi all,
I'd add Corydoras(ln9) panda and Corydoras(ln4) pygmaeus for the UK.

Corydoras panda breeds successfully in hard water so you often see hobbiest bred ones for sale in this area (Bath, Swindon, Bristol).

Re: Fish spawning with high nitrates?

Hi all, The first thing I'd say is that I practice nutrient depletion, and I use plant/microbe filtration as an essential part of this. I don't measure NO3 (it is much more problematic than most people realise, even with analytical quality equipment) , but I use a mix of conductivity measurement and...

Re: Tiny eel-like catfish from north east India. Looks like chinese dragon.

Hi all, That cat-elog is a really incredible resource, I was able to find the exact species within minutes. Thanks a lot, they are sub adult Olyra longicaudata. Looks like they really do stay roughly this small so glad I've not got a tank buster on my hands. Seems like I might want to give them a bi...

Re: Fish spawning with high nitrates?

Hi all, I think the real problem is untangling the effects of NO3- ions on their own, rather than as the smoking gun of previous ammonia and nitrite levels. I think this accounts for some of the startling difference in levels quoted, the Zebra Danio ( Danio rerio ) reference used sodium nitrate (NaN...

Re: Fish spawning with high nitrates?

Hi all, The first thing to say would be that we don't know what the safe level of NO3- is for the fish we keep, but my guess would be that the issue is with the test kit. Do you have access to an Ion Selective Electrode? The reason I think it's the test kit is: You only have about 200 ppm TDS, and i...
