Wow. That's pretty cool. I have had African cichlids for the past 16 years and always walked by them. Now that we have something cool rather then just the bowl we want something cool to put in it as well. Are these shrimp expensive?? I don't mind paying more for something that won't hide all the time. Thanks for the knowledge.
You're welcome, I really LOVE shrimp & inverts (you might have guessed).
I bet keeping these is as much different from Cichlids as night and day, other than the tank and water part!
Hikari has Shrimp Cuisine (kinda expensive online prices are least cost, around $8 or 9D) which I use along with many other things. You can use Hikari omnivore bottom feeder wafers, but they just need tiny amount of food at a time so they don't cause ammonia, etc. and kill them. You can cut up some of the wafers to make feeding easier. Figure the amount they can eat in one meal is around the size of their eye, probably a little more but you can tell that to your girls so they don't want to over feed. So a little food will go a long way. You could feed them that tiny amount 2-3 times a day.
The objective is to not have food laying around. And i usually skip feeding once a week or if they ate a lot the day before. Feeding will be more needed in the new tank that doesn't have much in the way of biofilm. It is good for them to forage later with a more established tank/bowl.
I would recommend medium to dark natural brown sand to black because this darkness allows the shrimp to feel safe coloring up all the way and will likely be brighter as they try to match their color to the darkness of the substrate.
Here the regular cherries run around $1.00 from local hobbyists, but around $3-4 at the LFS. Local hobbyists will usually do something like 12 for $10.
Enjoy. Hope the girls like the idea.
They also like small water changes to keep water content levels stable. Only enough changes to keep water clean and safe parameters. In other words you don't have to frequently change the water just for the sake of changing the water. they like stable parameters more (but safe and clean).
They eat algae and microscopic stuff but in a new tank you don't have microscopic stuff growing in there.
