First Sulawesi Cardinal Tank

Recommended Posts

KeenShrimp

Yep, I have to choose between buying shrimp stuff or a fancy camera and the shrimp always win- please excuse the photo quality.

This tank is now 2.5 months old: It's not pretty at all as I cannot cover bits with plants and am too worried about upsetting these guys to scape it. The ramshorns will be removed at some stage, but I am messing with the tank as little as possible.

I was very nervous about starting a Sulawesi tank as I read that they need stability. I wanted overfiltration, and as much of it that I could stuff in a small tank as I could. So I took a 29 litre Animates desktop tank and altered the filtration: I cut a 2cm x 1cm window where the filter intake slot was and covered it with nylon mesh and coral glue to increase water circulation (the solution does not look as classy as it is efficient). I also wanted something better than a sponge filter as my second filter: I bought an Acrylic corner filter: upon receiving it I noticed that the factory didn't even put intake slots in the filter, so it was just blowing bubbles and not circulating any water at all. I cut my own holes, rearranged the sponges so that shrimplets can't get sucked in. Then I stuffed that puppy with Eheim substratPro and a few other bits (yup, all I need now is a fake Nemo, suspended from fishing line to complete the plastic look :(, but it works like a charm and that water is crystal clear.

Pisces black inert quarts in the bottom. MarinePure filter media in the built-in filter. I have to thank very patient Chelsea @The Tech Den: I emailed her explaining that I wanted a reef shelf/base rock that I could prop up and grow algae on and have the shrimp hang upside down at the bottom- she emailed me photos and measurements and we found perfect rocks for cheap as chips! Next I harvested every algae type from 4 other tanks and stirred it into the water. 6 weeks later, I had lovely algae cover over the large rock. The corals in the photo are genuine coral skeletons.

I use Sulawesi 8.5 due to improved formulation, and now I am a sucker for boiling the salt solution mix on the stove for an hour when mixing my water, but the shrimp are looking very happy. If you have not used SaltyShrimp Sula 8.5 before: that stuff does not dissolve, no matter how much air you pump into a bucket it will be as white and cloudy as skim milk! I boil it on the stove, use 3 times the recommended amount, let it stabilize for a week with a heater and ensure that GH is 8 before it goes near the tank. The water is then crystal clear and the sediment has sunk to the bottom of the bucket.

The shrimp photo below are of Bonnie and Clyde. They went hiding when I took the insulating towels off the tank ( it's freezing in Canberra). The breeder of these beauties is @JPN07- how gorgeous are those blue dots on the body?

They get fed every 3 days with Shrimpy Daddy Sinewy cereal. Micro amounts of trace minerals/nutrients and probiotic solution is added every day as well as weekly minerals ( ShrimpyDaddy) and Vivace (ShrimpyDaddy).

I will be getting more Cardinals soon so that I can have an actual little colony.

Good work. I must be the only one I know that just dumps the Sulawesi minerals straight into tank lol Might explain my slow reproduction rate.

@NoGi, which salts are you using? 7.5 or 8.5? I bench-tested the 8.5 for various  dissolving options, and when I added it to the buckets without properly boiling it first, the GH-creep was all over the place, including TDS in the ones I had dissolve naturally for two weeks, and because SaltyShrimp is so darn hygroscopic, I don't measure it out by weight, so the only sure way of ensuring the Sulawesi replenished salt is stable at GH 8 that I found is the boiling method. The water is also crystal clear that you replenish with after it has been boiled and the sediment sinks to the bottom after a few days of heating....

I use Salty Shrimp Sulawesi Mineral 8.5. I generally grab a small plastic cup, put in required scoops, mix a little water from tank and pour in. Tanks goes freaky white and then all clear by next morning.

Almost always, I see fresh moults from my natives so something is working right I guess. My sulas, natives, snails and crabs don't seem to have an issue.

I don't measure GH so the creep you are seeing could be present in my tank too.

      Another thing you can do to avoid rescaping: Just take some of the fresh soil and put it in your filter.

      Thx ^^

      Hopefully the fish has just damaged itself as you say, mine do that sometimes, although the changes in the water will undoubtedly have caused them stress and the water they prefer was the water you started off with? There are sections on this forum dedicated to fish, I used it when I decided to try a Betta and got great advice from JayC and this Betta is doing way better than any I have tried before because of all the different things I did/do this time! https://skfaquatics.com/forum/forums/forum/116-fish-keepers/ Great to hear that the shrimps are doing so well. I think it is natural for the berried shrimp to hide away when they are near to birth as it protects the newly hatched shrimps when they are born, and the babies don't move far when they newly hatched either. There would be little to gain at this stage in getting more shrimps before getting a bigger/new tank, it may even be detrimental? I admit to being lazy sometimes and not topping up the tank between weekly maintenance/water changes (disgraceful really as I keep a 1litre bottle of RO water right next to the tank anyway), in which case I end up taking out 2litres and putting back 3litres at the next change, but need to make an allowance for the fact the TDS will change. When I set up the new Taiwan bee tank I measured the water I put into the tank at the start (assuming the measuring jug is anywhere near accurate) so that is how I know there is 28litres in the 35litre tank - it is a good idea to do this WITH A NEW TANK (but with everything in the tank, heater, filter substrate etc) as it is so much easier to do at that point anyway. I did the same with the Betta tank and that has 20litres in a 25litre tank (the one you were thinking of getting at some point). Without the exact figure to put in the spreadsheet then it won't be 'accurate (can still be used to give you as near an idea as needed though)', especially on a small tank! It works to the digit with mine. Even if you empty the tank and refill it probably won't be that accurate as the soil will have absorbed some water, so best do it first fill of new tank. Your water parameters are looking good and pretty much there now so all else being well you should be able to go back to once a week maintenance/water change. I don't know much about Nitrite/Nitrate as I have never had any readings, apart from the old fish/cherry shrimp tank which has always been 50 nitrate for years, probably because there are too many fish but there has never been a problem in that tank? PURELY AS A GUESS I would think the duckweed may have caused the problem/imbalance, but that is ONLY a guess based on I used it once and swore never again, I use water lettuce now, though that isn't perfect either as the routes grow so quickly that I have to trim those every week, but still a lot easier than duckweed.  Simon

      Thanks JayC, I think it is called a Geode, that was what it was sold as when I bought it in US many years ago though it could be something else? I think it is some sort of meteorite? Hopefully, as you say, now it is removed the PH may start to drop and I have put one in some prepared water to test in a week. I will also just see what happens with prepared water left out for the same period just to see what happens with that. Simon

      Those are very good quality shrimps and photos. Simon
