20g EE 5-6in
10g EE and Sand 4-5in
2.5g EE 3in
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?
The 20 gallon and the 10 gallon's temperatures usually read 76 and the 2.5 at 74 degrees.
The 20 gallon's humidity is always 99 percent so much so that my battery opperated humidity gauge's screen is full of water and the 2.5 gallon is always at 99 but the gauge isn't broken and the 10g is usually in the mid 80's
3. Is a heat source used in the tank? If so, what?
All tanks have a UTH that covers half the bottom of each tank
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)? All tanks have both salt and fresh water and i use declorinator/de-metal ionizer ?? and i mix the salt water with declorinator and the salt equal to the bottle's recomendations.
5. What kinds of food do you feed and how often is it replaced?
1/4 teaspoon of almonds, rivershrimp, crabby food, cuttlebone (every crab is molting except 3 and they can't get enough of the cuttlebone after a healthy molt) and every once in a while i give them leafy greens and fruit I'm currently waiting to get my grandma to dehydrate some fruits and veggies for a more balanced diet. Dried gets replaced every few days and the river shrip gets replaced daily if not sooner.
6. How long have you had the crab and what species is it, if known? All mine are Purple Pinchers and I've had the issued ones for over a year.
7. What type of housing are the crabs kept in, what size is it and what kind of lid is on the housing? Glass aquarium 20 gallon and a metal mesh top covered to keep in humidity.
8. How many crabs are in the tank and about how large are they?
20g has 3 medium-Large, 1 jumbo, 1 teenie
10g has 1 jumbo
2.5g has 3 teenie, 1 small
9. How many extra shells are usually kept in the tank, if any?
i have too many teeny-small extra shells to sit and count in both the 20 gallon and 2.5g for one post. 2 shells in the 10g and 3 or 4 medium-bigger shells in the 20 gallon.
10. Have there been any fumes or chemicals near the crabitat recently?
I keep hand sanitizer next to the crabitat for easy cleaning after handling but they have never come in contact with it. So no.
11. How often do you clean the tank and how? If the water dishes are empty or has dirt in it i rinse it out in the sink and dry it off completely then refill it. All decorations are plastic or natural hemp and i will deep clean it when i get a new tank. When they are all done molting i will stir around the EE to make sure there is no mold and make it like new and not compressed at the bottom. And when it gets too humid in the tanks i take a dry wash cloth and wipe down the dirt and water droplets from the glass walls.
12. Are sponges used in the water dish? If so, how are they cleaned?
Rarely. When i do use them i change them every day, letting the old one dry to be microwaved and putting a new clean one in.
13. Has anything new been added to your crabitat recently? A moss pit which my Matty Pumpkin loves so much he molted in it.
14. 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.)? Nope
So I have a pretty big PP that's never fought or pinched me, Octavius, my big boy. He's a Jumbo and molting for the first time in a year ina half/2 years ?? and I didn't iso him. Now another one of my crabs (Junior/PP/Medium) is digging above him, he's right next to him at this point and idk if my big boy is safe. Will he just go somewhere else to molt or should i worry about canibilism? I moved Junior away from Octavius but he crawls back and digs some more and i can't fill in the hole for fear of suffocating Octavius. I can't iso either of them right now because my second biggest is isolated in a 10 gallon awaiting a nice molt and hopefully a decision on shells (changing back and forth ALL the time) before i put him in the main, and 4 teenies in a small 2.5 gallon and there's no way Junior could fit in there (don't judge I'm currently waiting on the funds and/or one to come up in auction to upgrade tanks)
UPDATE: Junior has currently stopped digging and he is leaving Octavius alone for now.
I recommend you not go below a height of 20. With 10in of sub, you will want at least 10in of viewable space, so that you dont have just a tank full of sub
