PostSubject: Setting up for Hara jerdoni.   Wed Feb 22, 2012 1:57 pm

Here's my latest project. I have a ten gallon tank which has been running for seven years. When Ben was here taking all the fish out of it a few weeks ago, I told him the tank was coming down.

So for a few days it just sat there all forlorn with only the black sand and some floating brown dust. Obviously I don't have enough to do *lol* because I got the idea to take out some of the Cryptocoryne from the 20 high and plant it in the 10 gallon. The 10 G was starting to look good again. I decided to set it up as a species tank for Hara jerdoni.

Hara jerdoni is a species of tiny Indian catfish which goes by the common name of mini moth or stone catfish.
This pic shows one in my 29 gallon tank.


Hara jerdoni
That pic is a few months old because the 29 G is now history and all the Hara are in the 75, where I can't see them!
That's what decided me to set up a new tank for them.

So far there's about 2.5 inches of Tahitian Moon Black Sand, three large Cryptocoryne wendtii (green) plants, two small pieces of wood planted with sprigs of Java fern, and a big piece of wood at the back shaped like a T-rex.
I don't know why it's important to mention the shape - it just is. *lol*

I have taken new pix of this set-up and will get them on-line soon. Very Happy

They're very interesting. They stay mostly on the bottom, but can also be found hanging around on plant leaves. Buoyancy is an issue with them, therefore they have structures to keep them upright on the substrate.

They are sluggish and wiggly swimmers and not that hard to catch. I will recover as many as I can from the 75 and get a few more from a catfish buddy to fill out the colony.
Very Happy
Will post pix of the tank later - computer willing. *lol*

No to cichlids, I'm afraid. These Hara are much too small and slow. They need a species set-up with maybe one compatible mid-water swimmer. Even small Apistogramma wouldn't work because they would want the bottom for themselves. Wink

Thanks, Ben. I tried to load up the pix last night but my camera battery ran down!
Very Happy

I'm so glad the 10-gal has a plan, and this sounds perfect. Those fish are absolutely adorable! I love you

Well, I finally got some pictures of the new set-up uploaded.

Here is the way the tank used to look:


Notice all the oak leaf litter and the swordplants. Ben took the Dekeyseria catfish and the tetras from this tank, as well as the plants.

So then the tank was empty for a while ...


... for only a few days!


This is the new look still under construction.
A better photo was taken today but not uploaded yet.

Notice the turbulent water at the top. This is far too much waterflow for the Hara, who need a combination of well-oxygenated AND nearly still water.

Based on advice from members here, I've since cut some foam blocks and pushed them onto the intake tube to slow down the return flow.

Ancistra, love the setup! My blackwater tank is cycling with a few female bettas. I have lots to post, but I've been too busy with work and migraines:(

Sorry to hear that about the migraines. Sad That can be pretty rough.

Some better photos are on my computer but not uploaded to Photobucket yet. Will do ASAP. My small tank is a little too tannin stained from the one almond leaf and the one piece of bogwood, which I don't get because that piece of wood was in my 29 gallon Asian set-up for over two years! It's still leaching.

I'm aiming for a slightly alkaline tank with a few degrees of hardness to replicate the natural waters of the Hara. Some would be surprised to find that the wood and leaves don't lower the pH significantly, in this set-up, as long as the water changes are regular.

I didn't get a chance to mention that there are now five freshwater shrimp in this tank and three Danio margaritatus or celestial pearl Danios.

Two of the shrimp are Caridina multidentata, formerly known as C. japonica. The name Caridina japonica is now invalid but we all still call them "Japonica shrimp." These two came from PetSmart, btw and were about $1.99/ea.

The other three shrimp are also Caridina species. I need to look up their full names but the common names are "red crystal", "black crystal", and "orange tiger." I'm not sure about mixing so many varieties together but so far they are getting along well and chumming around together. The price varied by variety - around $6.00/ea.

The celestial pearl danios (CPDs) are rather stunning. As far as I can tell, there are two males and one female. They were $7.88/ea. at P.A.W. and I know that's a lot of money for such a tiny fish but they are just right for this set-up.

CPDs are from rather cool waters. Wintery conditions exist for much of the year in their natural habitat. The water is on the alkaline side and because it's mostly grasslands, plants grow right up out of the water.

CPDs are good companion fish for Hara jerdoni because they are tiny like the Hara, and enjoy the same water conditions.

This photo is posted to show the dense planting of Cryptocoryne and how it's growing in. It will be like a jungle in there in a short time.

Hara jerdoni like to hang around on and in plants much more so than wood.
For this reason, and also because it was staining the water too dark, I removed the big piece of wood.

The big piece of wood has been removed. Instead, several much smaller pieces with sprigs of Java fern (Microsorum pteropus) attached have been set around the tank. This is a better arrangement for the Hara, who prefer plants to wood. The ferns will grow slowly sideways while the crypts continue to stand tall, like grass. This will create a great deal of privacy for the catfish while keeping possible aggression between the male CPDs in check.

These three are ready to be transferred to the main tank.

That is one cool cat! I'd like to see a tank shot when you have time to do it proper.

Thanks. Very Happy The top-down shot is supposed to show how the plants form a canopy. The Hara, looking up, will see the enclosing leaves and gain a sense of seclusion and safety. They will think they're in their own tiny little forest stream. At least that's my idea. Obviously, I don't know what the fish are really thinking. *lol*

The crypts are spreading by sending up shoots here and there. I took out a couple of the wood/Java fern combos to make room. Everything's coming along really well.
Cool

Everything is going along great in this tank. The fish are nine Hara jerdoni (Asian mini-moth catfish) and three Danio margaritatus (celestial pearl danios). The CPDs are better in a bigger group so I look for more whenever I'm out. Rama (Skoolz of Fish) in Northside says he can order them for me so I may go that route.

My two freshwater shrimp are also well. Here is the red one:

Neocaridina sp.
There were five to begin with, but they worked it out among themselves and now I have two. Do not know what happened to the others but obviously they were eaten at some point. The two remaining are doing so well it's clear that two is the magic number.
So far, photos of the black shrimp and the catfish have eluded me!
Very Happy

Time for an update!
Here is a pretty good pic of one of the Hara j.

Hara jerdoni, mini-moth catfish.

Notice the brown and tan moth-like patterning and the "annululation" (I think that's the right word; it means separations) on the barbels.

I had a "Mini-moth Mini-tank" disaster a few days ago. After feeding fresh blackworms, two of my celestial pearl danios died and the next day one of the Hara was dead, also. It's possible the blackworms had nothing to do with it. I rinsed them twice before feeding.

That very day I had added another CPD male so maybe there was a fight? I didn't see it for myself and it doesn't explain the dead catfish.

Other than that, though, things are going really well. I won't feed live food again.

Nice looking Catfish Deb. I am sorry to hear about ya losing some fish, and then not really know the true reason they died is a bummer too. I been thinking bout feeding my Cichlids some black or blood worms. I also love the pic. I see the snail had to run over and get in the pic. lol.

*lol* about the snail! They say snails are slow but I've noticed they can book it over to the food pretty quick. Wink

Thanks for the compliment on the pic. It's very two dimensional but at least it's in focus. As to the blackworms, it's possible they were too large for these small fish and there was a digestion problem. I haven't lost any more fish so fingers crossed.

Frozen bloodworms seem to be a good food for my fish, so I may stick to that and not go live again.
Very Happy

Here's an update showing how the plants are growing in.
Notice all the little plantlets coming in at the base of the parent plant.


Cryptocoryne wendtii (green) or green crypt.

Green crypt grows about 14" tall.
The plants shown above are growing in a mature bed of Tahitian Moon Black Sand.
