Lethargic and not eating

[shawneeh]

Hi all,
I'm very worried about Tiny, our 2 yr old Hermie. He isn’t moving around and is acting lethargic. Today he seemed to be practically lying on his side. When I opened the lid and checked on him, he did sit up normally. But he doesn’t seem well.

He was doing fine until we brought in Biggie Big about 4 weeks ago. Biggie is a lot bigger than Tiny (Tiny used to be the largest of 4, but he’s been alone for about 6 months - different story).

There’s 2 things I’m suspecting:
1) When Biggie came (a rescue) my husband put him in the tank in a large cage to keep him separate for a bit from Tiny but with the top off and Tiny crawled in the cage the same day. The next day I smelled a terrible ammonia smell. I removed Biggie's cage, which turned out to be the source (so bad) and the smell left the tank about 1-2 days later. Biggie is doing great. Maybe the smell did something to Tiny? (In retrospect I should’ve washed Biggie before putting him in.)

2) Biggie and Tiny seemed to be establishing dominance at first but I saw no aggression at all and never have. Just antenna feeling and crawling over each other. And that was only the first few days. Still, I wonder if there was a fight of some sort and Tiny got hurt and is recovering. I can’t tell if he’s injured but he can walk fine. I haven’t seen him have any food or water since Biggie came except one time I saw him in the dish of crushed eggshells, which made me wonder even more if he was hurt and craving calcium. Biggie is often near Tiny, cuddled up behind him.

I don’t know what to do to help Tiny but he definitely hasn’t been right since Biggie came in. Not eating/drinking far as I can tell and not moving if he can help it. He will walk if spooked, and seems to do so fine. I’ve noticed he’s moved from one hiding spot to another about 2-3 times. Biggie seems to always want to be near Tiny, cuddled up behind Tiny's shell. Again, he doesn't seem aggressive. But Biggie is always moving around, eating, exploring. But not Tiny.

Should I separate them by putting Tiny in a cage for a while? (I don’t have 2 tanks.)

Thanks!

Here’s my template:

1. What kind of substrate is used in your tank and how deep is it? Sand and cocofiber, about 4” deep.

2. Do you have gauges in the tank to measure temperature and humidity? If so, where are they located and what temperature and humidity do they usually read? Yes - humidity is 72-80%, temperature is about 80.

3. Is a heat source used in the tank? If so, what? Yes, several pads stuck to sides.

4. What types of water are available (fresh or salt) and how is the water treated (what brands of dechlorinator or salt mix and what ratio is used to mix it)? Fresh dechlorinated water and bottled salt water from PetSmart.

5. What kinds of food do you feed and how often is it replaced? Powdered crab food from Rehoboth, DE where I got Tiny, and he’s always liked it. Also give fresh food about 2-3 times/week. Replace it about ever other night.

6. How long have you had the crab and what species is it, if known? Had Tiny for about 2 years. He’s brown with a purple claw, not sure what kind.

7. Has your crab molted, and how long ago did it happen? Yes, many times. Though he’s been down several times, he's kept the same shell for about a year. Sometimes tries on a new one but goes back to the old. He needs to be in a new shell. There’s plenty to choose from.

8. What type of housing are the crabs kept in, what size is it and what kind of lid is on the housing? 20 gallon, glass lid.

9. How many crabs are in the tank and about how large are they? 2 in tank. Tiny is about 2” and Biggie our new rescue is about 3” more or less.

10. How many extra shells are usually kept in the tank, if any? About 10. Biggie has tried all sorts of shells on.

11. Have there been any fumes or chemicals near the crabitat recently? Yes – ammonia when Biggie first came but none since.

12. How often do you clean the tank and how? Not often. I did a thorough clean about 3 mos ago.

13. Are sponges used in the water dish? If so, how are they cleaned? I just put one in. To clean, I just rinse it out.

14. Has anything new been added to your crabitat recently? Yes, Biggie Big the crab.

15. Is there any other information you would like to share that might be helpful (anything that is regularly part of your crab care, playtime, bathing, etc.)?

It could be that smell. They are very sensitive to fumes and odors. Post on the emergency page. I'm sure you will get the information you need. I suggest getting a 10 isolation tank. You never know when you will need one. We always have one set up just in case
