Everyone says it's ridiculous that I want a 65 gallon tank for my hermies, but I feel like if I really want it and I save up the money for it then it's none of their darn business! So basically, this tank, with hinged lid and shipping, is going to be about $268. I have a really good spot for it, under my window (actually the only feasible place for it, it's like 4 ft long!) The tank is acrylic, and I was hoping someone knew about any differences or changes I'd have to make in heating/lighting. I'm pretty sure it wouldn't be good to have a UTH, but correct me if I'm wrong. I think it would melt the acrylic, right? And lighting/heating... I think, logically, it would make sense to have a heat lamp if there's no UTH, but I don't know how to do that with an acrylic lid. It has to be possible, because it doesn't make sense to not be able to heat an acrylic tank. Animals still need to live in them! Also, does anyone know if I should go with 100% EE, like I have now, or 50% EE and 50% Playsand/aquarium sand (whichever I feel more comfortable with putting in with the crabs). How much substrate do you think I'd need for a 65 gallon if I have 2 bigger crabs and one littler one? Right now the deepest my substrate gets is 3 inches. They're definitely like 2.5 inches, so I have a feeling I'll need about 2 blocks of EE per 10 gallons. Wow. That's a LOT of coconut fiber. That's like 13 blocks. Do you think that's about the amount I'd need though? What do you guys with big tanks use for lighting? I've heard about Moonglow bulbs, but I don't exactly know what they do. And what are your views on humidity and temperature gauges? I got one of each that I thought were from a reputable brand, but soon thereafter, I noticed water drops INSIDE the humidity gauge AND the temp gauge. Is analog really the best way to go, or do you think digital is more accurate? Do you need more than one of each if you have a tank as big as a 65 gal? I would think so, because there could be variations within the tank. Is there a brand that's better than the rest, or are they all just kind of crummy? Another thing, I currently have a mesh lid to my 10 gal and I covered it in plastic and it's rusting. I don't know how to deal with this because I know metal hurts them and I don't want the rust dripping all the way to the ground. Oh, and I've been wondering this for a while, should the saltwater dish be bigger, smaller, or the same size as the freshwater dish? Where do you get cholla wood? I have been searching and searching but I can only find it on ebay in lots of 20 sticks. Does the 3m adhesive work inside the tank to hold up a soap dish/shower caddy instead of suction cups? Does anyone know where to get good, cheap hemp yarn? I've called all the yarn places in town and none have any. There's some online but they're either really expensive, or the shipping cost is double what I would pay for the actual item. And does anyone know where to get suction cups with plastic hooks? neither craft store in my town has them. Has anyone heard of "Zoo Med Hydroballs lightweight expanded clay terrarium substrate"? Apparently you put a layer of this stuff down, then a layer of plastic mesh, THEN a layer of EE. It's little balls that look kind of like cocoa puffs (I'm fairly certain they wouldn't taste as good, though . It lets you make a waterfall in the tank with a small pump behind a cork wall and it supposedly makes it so you don't need a reservoir at the bottom of the waterfall, the water just soaks through the substrate and into the bottom of the tank where the hydroballs are to recirculate. It sounds strange, but in a fit of kindness, my mother bought them for me (they were on sale haha) THe bag also says that you can use it to create an underground water table for a "naturalistic terrarium" or use them to make an aquifer to increase the humidity. I don't know, but the bag makes it sound pretty cool. I just want to know if it's safe for my crabbies. Okay, I think I've exhausted my questions. Sorry if the length of my post intimidates any potential answerers, I just have a lot I want to know and I want to make sure I'm doing the best I can for my lil' hermits.
