Re: Shrimp Tank - Juwel Rekord 60 - Sulawesi shrimps
Hi all,
I've been impressed with the
Fissidens (I got it from Paulo), it has grown much faster than I expected grown low-tech.
If I was going to try and keep Sulawesi Cardinals (
Caridinia dennerli), I would go down the species tank route with a silica sand/rock rubble substrate. An inert substrate/additive like Akadama would probably also do.
I've not kept them, but I've seen pictures of their natural habitat and it looks to be a "short rocky lawn", heavily grazed by snails. The water clarity and general look is strongly suggestive of the marl lakes in the Burren, W. Ireland. Here the water is calcium carbonate saturated, but almost devoid of nutrients. I'd be tempted to use a small amount of shell sand and only fertilise with an N & P deficient mix (their native lake naturally contains K and Mg), aiming for an alkaline pH, but low conductivity.
The Burren lakes have a patchy carpet of
Eleocharis acicularis, and my planting would probably be only sparse
E. parvula and aquatic mosses, again the Burren lakes have a large number of these, and I would expect L. Matano to as well. Flora was recorded as "
Ottelia, Eriocaulon and Lymnocharus sp".

"
In the Towuti, Matano and Poso lakes you can find pH between 7,4 and 8,2 according to collectors and these shrimp appear to require the higher pH. the conductivity is at about 224 µS and the total hardness at about 6 DH. The water temperature is mostly stable at about 80 degrees F. in the deeper areas of the lakes, but in shallow water regions near the shore the temperature can rise to 84 degrees in the day. "
I'd also be keen on some snails, I'm sure MTS would do and some of the
Tylomelania sp. would be good. Probably
T. patriarchalis (below). I'd also add some leaf litter, I've got some
Eriobotrya leaves (Loquat) that would be good, the shrimps love them and they are very persistent.
Finally I'd set up the tank and then leave it for several months so that it was fully established and stabilised and a good biofilm had developed, ideally a very short "stubble" of filamentous greens.
