Reply With QuoteExcellent and I really like the Otto. Where did you buy the Cocama?
And how much did you pay for it? If it's ok to list it here.

Excellent and I really like the Otto. Where did you buy the Cocama?
I got mine from JZX.Originally Posted by Mir
may I know where you bought that acrylic dish that have the suction cap? I too have the same problem of food sinking and disapearing into the carpet of plants... did you DIY yourself??
I ordered it from eBay, cost around SGD$10+ for a set (incl. postage) which includes the dish and feeding tube.
There are quite a good selection of various dimensions available, just search "acrylic shrimp feeding dish" on eBay and you should see all the listings, check through to find the good deals. There are also a few sellers who only sell the dish individually too (if you prefer that arrangement).
The only part that i DIY was using a suction cup to attach the dish on (instead of using the feeding tube, due to otocinclus getting trapped in it and unable to reverse out), what i did was just assemble the included acrylic nut and bolt in the dish, and then push the exposed part of the bolt into a suction cup with matching fit.
Added a group of Corbicula Fluminea (aka Golden Clam) to the tank...
I've actually been keeping them for the past few months in another sand-based tank, but its currently being rescaped, so i transferred them over to this tank.
I wasn't keen on letting them dig into the soil substrate in this tank and mess up the plants though, so i created a suspended "sand bed" for them to live in. Its basically made from an acrylic feeding dish filled with a layer of sand and attached to the glass wall.
The sand bed is positioned in the path of the filter flow, as these clams are micro filter feeders and do best with water constantly circulating around them.
Here is a close-up photo of the clams in their sand bed...
These clams are quite active creatures, they will move around the dish and dig into the sand using their "foot"... but they aren't able to climb over the edge of the dish (and disappear into the plants and soil below), so its much easier to keep and observe them this way.
Nice. Might be willing to try this as well. I use to have a couple of them in my previous tanks but they all dug so deep into the substrate that they eventually died off one by one.
And when they eventually do it causes a huge ammonia spike which are detrimental to shrimps.

Yeah, clams dying while hidden inside the substrate is like an underground toxic dump, will leach out lots of ammonia as they decompose.
I figured that putting them on a thin substrate layer would be better, in their previous tank the sand layer was only 0.5cm thick too, so they could dig in abit to feel safe but i can still check on them easily at a glance.
When i first got them i also expected them to die off quickly, but after a few months i was surprised to find all of them still alive and active in the tank, even though i never specifically feed them anything. My only guess is it might be because the tank i put them in had already been running for more than 6+ months, so it probably built up enough floating micro algae and phytoplankton to sustain them for a while.
Which lighting are you using?
Just 1 x Up Aqua Z-Series Pro LED Z-20 lightset (older version).
Bro can get photo of the current tank state? Need inspiration ☺

Thanks for the abundant information. Very nice.
This is interesting, what do you feed them with?Here is a close-up photo of the clams in their sand bed...

To date i haven't specifically fed them with anything for the past few months... i guess they are just filtering and consuming all the free floating microscopic particles of food and algae that circulate around the tank. I just treat them like plants and make sure they get ample water circulation from the filter, that seems to work well so far.
I've read that some people culture green water solutions and then feed it directly to the clams using a pipette. It would be interesting if they were introduced into a tank with green water, see how effective they can be at filtering and consuming the algae (might be an alternative to UV sterilizer for green water conditions).
Very beautiful tank! I love it! Double Thumbs up!
Still looks more or less the same... here is another photo i just took of it:
The only major change was i removed the Anubias sp. 'Petite' carpet a few weeks back to aquascape another tank, which created a gap in the middle... so i harvested some bunches of Eleocharis sp. 'Mini' and re-planted them into the empty area to fill it in.
No change in lights, Co2 and ferts. The background plants are trimmed every 1-2 weeks to maintain their fresh growth (or when i'm less lazy). I recently did a big trim on the Blyxa Japonica and removed alot of it, so it looks less crowded.
I frequently leave this tank unattended for days and it just runs on its own, so its been a relatively low maintenance system so far.
Woah, the tank is coming in nicely there
Advice from boss Felix
I got the clams from C328... if i remember correctly, they are usually hung in small packets amongst the bags of feeder fishes and snails.Woah, the tank is coming in nicely there
Thanks for the update bro. Looks great!!
