Hi! I'm completely new to shrimp keeping. I bought my shrimp as "rili blue". If that's true, then they are of a lower grade, aren't they? Some are dark blue, others seem more jelly like, some don't have a clear part at all. One of the first offspring came out as this clear brownish shrimp. Can somebody help me out? What is the type of these shrimp - and are there more than one? If they keep on breeding, will the blue go away and the brown come out more often? I hope the pictures are clear enough. Hard to photograph and hard to meet the maximum file size.

Many people have a tank for cull/reject shrimp so that would be fine! Or if you have a fish tank you can put the culls/rejects in that! Simon

Thank you for the quick answer! Would it be alright to remove just one shrimp and put him into a different tank/tub? Will he be alright there, all alone?

Crabby, Its all good. That second tank discussion is already happening!

There are other sources of Calcium for your shrimp apart from dosing Calcium sulfate or dropping shells and cuttlefish bones into the water column. These sources come from the foods we feed the shrimp. These are all natural sources of food, so should be okay to feed your shrimp, just be careful you wash them properly and ensure no fertiliser/chemical residue is on the veg/fruit. If you grow it yourself, you will be sure of what was sprayed on the plants. Here is a list of vegetables and fruits by mg of Calcium content per 100gm of food. Vegetable (mg Ca) Arrowhead 1 Chives (per tablespoon) 2 Peppers, Sweet 6 Alfalfa sprouts 10 Pumpkin leaves 15 Asparagus 14-28 Coriander (cilantro) 16 Chard, Swiss 18 Radish seed sprouts 19 Lettuce, Cos, Romaine 20 Lettuce, Romaine (100g) 20 Squash, Zucchini 20 Jerusalem artichoke 21 Pumpkin 24 Endive 26 Squash, Summer 26 Cauliflower 28 Purslane 28 Radishes 28 Carrots 30 Eggplant 30 Cabbage 32 New Zealand Spinach 32 Kohlrabi 34 Lettuce, Looseleaf 38 Peas, Green 36 Turnips 39 Cress, garden 40 Watercress 40 Broccoli 42 Mung bean sprouts 42 Celery 44 Beet greens 46 Snap beans 46 Parsnips 47 Spinach 56 Mustard Greens 58 Green Onions 60 Peas, Edible pod 62 Rutabagas 65 Celeriac 68 Chinese cabbage 74 Parsley 78 Salsify 80 Borage (Starflower) 82 Okra 82 Kale 94 Lettuce, Iceberg 102 Dandelion greens 103 Turnip Greens 105 Kale, Scotch 137 Chicory greens 180 Mulberry Leaves ~200 Collard Greens 218 Fruits mg Ca Plum 4 Peach 5 Nectarine 5 Casaba Melon 5 Blueberries 6 Honeydew Melon 6 Banana 6 Cranberries 7 Apple(with skin) 7 Pineapple 7 Persimmon 8 Watermelon 8 Mango 10 Grapes 11 Cantaloupe 11 Pear 11 Grapefruit, Red & Pink 11 Grapefruit, White 12 Apricots 14 Tangerine 14 Strawberries 14 Sweet Cherries 15 Raspberries 22 Papaya 24 Lemon (peeled) 26 Kiwi fruit 26 Blackberries 32 Lime 33 Orange 40 Seedless Raisins 49 Just a word of caution. These foods contain Phosphorous and could have an ill effect on your water quality. It might even cause an algal bloom if the levels of phosphorous become too high. Common sense applies when feeding ... not too much too often, and if there are any leftovers, remove it. For those Phosphorous conscious people out there, this is a table of Calcium to Phosphorous ratio: Calcium:Phosphorus Ratio - Vegetables 14.5:1 -- Collards 10.0:1 -- Mulberry Leaves 7.5:1 -- Spinach, Mustard 4.5:1 -- Turnip Greens 4.3:1 -- Lambsquarters 3.2:1 -- Dill Weed 3.0:1 -- Beet Greens 2.8:1 -- Dandelion Greens 2.8:1 -- Chinese Cabbage (pak-choi) 2.7:1 -- Lettuce, LooseLeaf 2.4:1 -- Mustard Greens 2.4:1 -- Parsley 2.4:1 -- Kale 2.1:1 -- Chicory Greens 2.0:1 -- Spinach 2.0:1 -- Watercress 2.0:1 -- Cabbage 1.9:1 -- Endive 1.6:1 -- Celery 1.5:1 -- Purslane 1.4:1 -- Cilantro 1.4:1 -- Lettuce, Butterhead 1.3:1 -- Okra 1.1:1 -- Swiss Chard 1.1:1 -- Turnip 1.1:1 -- Chard, Swiss 1.0:1 -- Squash (winter, all varieties) 1.0:1 -- Green Beans 0.8:1 -- Lettuce, Romaine 0.8:1 -- Sweet Potato 0.8:1 -- Rutabaga 0.7:1 -- Broccoli 0.7:1 -- Cucumber (with skin) 0.6:1 -- Carrots 0.6:1 -- Squash (summer, all varieties) 0.6:1 -- Carrots, Baby 0.6:1 -- Brussels Sprouts 0.5:1 -- Cauliflower 0.5:1 -- Kohlrabi 0.5:1 -- Pumpkin 0.5:1 -- Alfalfa Sprouts 0.5:1 -- Parsnips 0.5:1 -- Peppers,Green 0.5:1 -- Peppers,Red 0.4:1 -- Sweet Potato Leaves 0.4:1 -- Beets 0.4:1 -- Asparagus 0.2:1 -- Tomato .02:1 -- Corn, White Calcium:Phosphorus Ratio - Fruits 4.8:1 -- Papaya 2.9:1 -- Orange 1.8:1 -- Lime 1.8:1 -- Raspberries 1.6:1 -- Lemon (no peel) 1.5:1 -- Blackberries 1.5:1 -- Grapefruit, White 1.2:1 -- Grapefruit, Pink and Red 1.2:1 -- Tangerine 1.0:1 -- Pineapple 1.0:1 -- Pear 1.0:1 -- Apple (with Skin) 0.9:1 -- Mango 0.9:1 -- Watermelon 0.8:1 -- Cherries, Sweet 0.8:1 -- Grapes 0.8:1 -- Cranberries 0.7:1 -- Casaba Melon 0.7:1 -- Apricots 0.7:1 -- Kiwi 0.7:1 -- Strawberries 0.6:1 -- Cantaloupe 0.6:1 -- Honeydew Melon 0.6:1 -- Blueberries 0.5:1 -- Persimmon, Japanese 0.5:1 -- Raisins, Seedless 0.4:1 -- Peach 0.4:1 -- Plum 0.3:1 -- Nectarine 0.3:1 -- Banana So Collards are a good choice as they have a high Calcium to Phosphorous ratio While Bananas are not such a good choice as they a low Calcium to Phosphorous ratio.
