how many fluval shrimp granules to feed 25 cherries and 10 tiger shrimp?
***This post got long and rambly. To summarize, TLDR: how many fluval shrimp granules, and how often, would you feed 25 rcs and 10 tigers in the same, densely planted fluval ebi tank?***
I redid my 8gallon fluval ebi, which was my first shrimp tank. It was set up for about a year with 30 red cherry shrimp (but very high quality, basically painted fire red culls). I fed one fluval shrimp pellet per shrimp, each day. 30 pellets, every day. Way too much in retrospect.
I lost about half of them over the next few months, due to my ridiculous overfeeding. They bred, but slowly, maybe 3 surving to adulthood out of each batch. I had about 3-4 generations I think before they were wiped out.
I lost the rest when I placed some plastic pipes in the tank, to use as breeding tubes, which were listed as safe for potable water, but everything died within a week, so Im assuming it was due to a chemical contaminant.
So I left the tank fallow for a few months, watched the planaria and worms (side note, I had an infestation of herbivorous nematodes, they would work their way down my frogbit roots and eat off all the root hairs. I always found them interesting) and the single nerite do their thing, then finally I decided to try again. I redid the tank, let it cycle up over a month, and restocked it with 25 small (half an inch to 3/4) red cherry shrimp, and 10 large (1 inch to 1 1/4 inch) tiger shrimp.
So my question, I dont want to overfeed, but I feel like with that many shrimp, biofilm wont be enough. So how much should I be feeding? People say as much as they can eat in 3 hours, but even when I was feeding 30 pellets a day last year, it still was all eaten in an hour?
Any suggestions for feeding quantity and frequency? Anyone else use the fluval shrimp granules that come with the ebi?
The tank is a stock ebi, stock light, stock filter with a giant sponge tied to the intake with fishing line to cover the intake and save shrimplets, fluval shrimp stratum substrate, constant temp of 75 degrees, ph just under 7 out of the tap, and I dont monitor it, but stratum should buffer it to 6.5. Its planted with one giant stem of wisteria to hide the filter, a bunch of rotala carolianas, a softball sized clump of java fern, and a few small anubias on a extra holey piece of malaysian driftwood, another piece of malaysian driftwood with some moss, a small patch of dwarf hairgrass, and a small patch of crypt. parva, and some crypt wendtti. I just took a little bit of everything from my other tanks to see what would grow, and luckily its all doing well. So really, lots of places for biofilm to grow.
Thanks for any advice, its appreciated.
