I am so sorry.
Tank is looking good and shrimp are pretty .
How long has the tank been up, so in regards to the biofilm...or maybe lack there of.
I understand some rainwater (soft water), of just using water a little cooler than their normal water can help them get into the breeding mood. It is like the rainy season which triggers breeding behavior in nature.
I have tried this (several times when it seems they aren't doing anything) and they have SEEMED to respond well, but don't know if it was a coincidence...Ended up with saddled females and eventually babies.
Tank was cycled in May. Shrimp have been in there since June. Started with 3. Two weeks later added 5. Over the next two weeks 6 died. All deaths occurred AFTER molting.
Did some research, check gh/kh, added cuttlebone. Had 2 shrimp for a few months. Added 6 more. Over the next month 3 died.
Have 5 for the last month or two. I think they are all female (yellowish saddle on back).
A few of them are usually out exploring but most of the time they hide behind the DW unless I drop in a wafer or some shrimp cuisine. There is a moss ball in there but they ignore it. When they are out, they spend time on the DW/moss and sponge over the filter intake. I have diatoms growing on the sides (limpets feed on it). I used to see hydra, detritus worms, seed shrimp, and Copepods but for some reason I don't anymore. Just the limpets and some type of small snail with a rams horn type shell, however, they carry the shell flat and not upright like a rams horn.
Might check out AquaBid so that I can bump up the population to 15-20. The price at the LFS is high ($4.29 each).
Check here there are a couple people who usually have them available for around a buck each for regular cherries and 2 for Fire red...
Maybe your tank needed more maturity at the beginning. Do you change the water very often? they don't generally like too much water changed, or very often. Hydra aren't good for shrimp, they can sting and kill them. Are you sure they are gone? They usually don't just disappear...
I will check with members about obtaining shrimp.
WCs take place about every two weeks. 25-40%.
Well, they hydra (and seed shrimp, copepods) reduced in numbers over the last 3-4 months. Just today I was checking out what still in there and all I see are the odd little snails and limpets. Hydra gone is a good thing. But are they gone because the seed shrimp and pods are gone? I assumed having seed shrimp and pods around was a good thing. Also, I don't see detritus worms anymore. Odd. Nothing has changed maintenance wise except I started using a gravel vac about a month ago. But the population drop occurred well before this.
Thanks for the shrimp compliments! I just need more of them. The tank is always evolving.
Still experimenting with the layout of the new stones. Will try to add a few more and/or rearrange them to give a more natural appearance. If I squint they look like dinner rolls! Gosh, that's making me hungry...time for a snack.
As for your stones...dig out a few handfuls of substrate then try sort of tossing the stones into the depression, then drop the handfuls of substrate back on top of them. After this, they should look more like they were there in the scape naturally.
You can slightly adjust the stones more to your liking but the point is to keep them looking like the top soil eroded away from the stones.
The stones do look better Yeah it is a little in a line there, I would jog one of them back a little.
More importantly, what are you thinking about it? It is your tank...?
