do you think that my fiddler crabs would enjoy this??? have you had any experience with these before??

is it good quality?

i am thinking of getting a couple from my LFS (they come in packs of 2) and feed them to my fiddler crabs...just to give them something else. Do you think it would be ok for them??

I dont know about crabs, but I had these when I went to Pennsylvania for a week. It was for my neons and oto's. Didn't muck up the water and my fish were alive when I got back, so seemed to work good :)

i have some homemade food recipes you could try, it would be a lengthy post, so let me knowif you want me to share.

Megan...was most or all of the food gone when you got back???

I had 5 tetra's and 2 oto cats. It was about 1/2 gone when I got home.

ok...well i think that i will buy the pack of 2 for like $5 and see how it goes. I have in the tank:
6 fiddler crabs
50+ feeder guppies
10-25 snails
4-6 shrimp

So i think that it will get eaten really fast. lol.

I tried those gel blocks. Fish didn't touch them.

the best thing about homemade food is you can control the portion size easily....i make this stuff for all my inverts and feed it occasionally in my community tanks as well...the cories go nuts for it. here is the lengthy post:
Snail Jello
1 can of baby food (4-6 oz)
1 tsp+ fish food (may be omitted)
Calcium/vitamin supplements (I use 1tsp Jurassi-reptical powder w/out phosphorus)
1 packet (= 1 tablespoon) unflavored gelatin

You can select any fish food and any flavor of baby food that you like. Try to find baby foods with at least 4% calcium (vegetable medley has a higher %), either fruit or vegetable types are find. This is a good way to feed fish foods that are good for snails but don't sink, like freeze-dried shrimp, or fish foods that have a strong smell when cooked in other recipes. You can mix in much more than a teaspoon of fish food, and including the ingredients of a "snail trail mix" instead of a single fish food would make this snail treat more nutritionally complete.


Open the baby food and pour it into a small bowl. Heat the baby food in the microwave for 60 seconds (caution, it will be very hot).

Stir in the unflavored gelatin (add it slowly to avoid unsightly clumps of gelatin; don't use a blender or you risk creating air bubbles that will make it float) crushing any lumps with the back of a spoon.

Add calcium supplements and vitamins if you have/want them. Stir thoroughly.

Pour this mixture into a dish with a flat bottom (tupperware-type containers work well; if you are doubling or tripling this recipe, you might consider a pie pan).* Fold in your fish food(s) if you are adding any.

Refrigerate for several hours, then return and cut into cubes.

One jar of baby food yields a good handful of snail treats. Keep them refrigerated until serving. These sink and hold up pretty well in the tank, but as with any food, large uneaten portions should be removed after the snails have finished. These can be frozen for up to a month.

*You can use an ice cube tray to create big treats for a tank full of snails. No slicing is needed in this case.

Calcium Blocks for Picky Snails

Another gelatin/calcium recipe.

1 tsp unflavored gelatin
5-10 calcium pills, crushed
1 tbsp honey
(optional) other vitamins, low-sodium seaweed powder, etc

-Dump gelatin into a small bowl. Boil 1 cup of water, and use as little of it as possible to dissolve the gelatin ( I used 3 tablespoons or so).

-Let it cool for a few minutes, then mix in the honey, calcium and optional ingredients. This step is kind of tricky- you want a thick paste, but without any air bubbles in it. Try kneading it instead of stirring.

-Flatten into a circle about ľ of an inch thick. Put it on a sheet of waxed paper, and put it in refrigerator for a few hours. Once it is set, slice into thin chunks and place the chunks (not touching one another) onto a piece of waxed paper.

-Put them into a warm, dry room. If you have a fan handy, you might as well point it at them (if not, donít worry about it). Leave overnight. By the next morning, they should be completely dry. When these blocks are done, theyíre hard as a rock, and sink like one too. You could probably use a dehydrator, if you have one, but I found that they dried very quickly without one.

-Donít make these when itís humid out. They wonít dry.

-Cutting it into small chunks is vital. If you donít, it either wonít dry at all, or itíll dry into an unbreakable shell of calcium with a gooey center.

-I chose to use honey in this recipe because the snails seem to love anything sugary (thus attracting a picky, injured snail), and honey has been shown to have antibacterial properties, so I figured that might help to postpone the decomposition process while theyíre drying out. Other sweeteners or fruit purees would probably work, though.

In a food processor:
big handful of good quality dog bones that are not full of preservatives
handful of Science Diet Catfood (or any premium brand)
one ripe banana
cup of fresh spinach leaves
handful of chopped carrots
2-3 eggs with shells
2 scoops of powdered calcium

Grind up the bones and cat food until powdered, add other ingredients. Make a thick batter. Drop by spoonfuls onto greased cookie sheets, flatten as low as they will go with fork (spray fork first with Pam so batter doesn't stick)
Bake at 250 degrees until hardened. Remove from sheet and cool on racks, store in freezer.
You can add fish food, freeze dried shrimp or bloodworms, etc to this. (Warning, any fish foods will make your kitchen STINK while cooking.

another cookie recipe:
Blend in a food processor:
1 cup dried cat food
handful of brown rice
handful of oatmeal
1 clove garlic
6 calcium pills
3 eggshells
handful of assorted fish flakes, pellets and wafers

Boil for about 30 minutes or until soft:
2 carrots (and greens) chopped
5 leafs romaine
13 dandelion leafs
handful green beans

Drain and mash the veggies and mix with the dry foods. Then you can add:
1 banana mashed
1 peach mashed
1 pear mashed
1 small jar baby food
mixe this all together, and spread it out on a baking sheet, then roll it flat with a roller. the oven was set to just below 150 degrees - the lowest my oven could handle. It took pretty much the whole day to dry. This is another stinky recipe.
Substitutions can be made for veggies or fruits.

my pleasure, with most of them you can substitute fish foods/invert foods or veggies for fruits etc...they can typically be frozen for a month or so which is nice as well.
