Hello all,

I just joined the forum in hopes to share my experience and gain knowledge and expertise from all of you with far more experience than I have.

Basically, I have a 29 gallon aquarium that was already cycled with other fish (6 silver scats and 3 silver dollars). Believe me, I know I had way too many fish in the tank that was way too small for them, and don't think I am planning on keeping my fire eels in that tank for any extended period of time.

So, I know that the scats need to have brackish water, and eventually should be in a full marine environment, and I had them in a 1.005 SG. Mixing the salt into my water change water got old pretty quick so I decided to take my fish back to the local fish store and give them a chance to end up with an owner that can provide them with better care.

So, to get to my point, I traded them for two 4" fire eels. I had done a lot of research on them and know that they can easily reach between 30-40". I do currently have them in my 29 gallon tank because they have been extremely hard to find, especially at a size that small (which is what I wanted).

Prior to making the trade I had already talked with my wife about spending some of our tax return money on a larger aquarium and I have already been searching craigslist for some good deals. I have several good leads on some 220 gallon tanks and should be getting my tax return within the next week or two. Once I get the tank I plan on using Tractor Supply black blasting sand as the substrate and adding some driftwood and working on making the aquarium a low tec planted aquarium. As of now, I plan on using a sump and setting it up for easy maintenance. One of the few 220 gallon tanks I am looking at is already drilled.

Once I have the 220 gallon set up I plan on using the media out of the 29 gallon tank and putting it into the larger tank filtration and immediately moving the fire eels into that tank. They will be the only inhabitants for quite a while. Eventually, I plan on making the 29 gallon a bare bottom tank and using it to grow out a few discus at a time and adding them to the 220 gallon tank until I have between 8-12 discus. That is my main plan for the stocking and I don't plan on adding anything else except for possibly a smaller species stingray later on.

So, this is my plan and it pretty much centers around these fire eels because shortly after I learned of their existence they became my favorite freshwater aquarium fish and I have been researching and looking them up ever since.

So, as of now, this is my plan for these amazing little guys (who probably won't stay little for long) and I would love to hear what you all think about it. I am sure I am missing some things and I welcome any knowledge you all can offer.

Thank you all for your time.

First off, welcome to the forums...

Now onto your Fire eels...

First off, i would possibly advise against using Blasting Sand as a substrate, since it can be quite course with lots of rough edges which may end up hurting your eels in the long run, as they do like sifting through the sand at times...

As for keeping 2 in the same tank, it seems like you'll be asking for trouble as they get older, considering normally people tend to keep just one mainly due to their size, and the fact as they get older, they can fight with each other, so you may need to put that into consideration...

Also, when do you think realistically you'll have the 220G up and running??? coz these guys at that size do grow very quickly, and would appreciate the extra space definitely sooner rather than later ;)
 
Thank you for your information. I was affraid of the blasting sand being too coarse. I will have to forgo the black sand and find something a bit softer. I really like the look of black sand but if it is not available in a soft but economical option I will not be able to use it. I know there are black sands out there that are for aquariums (that is actually what I have in my 29 gallon right now) but since I'm going to be using it to cover a 220 gallon aquarium, it will need to be a cost effective option. Will a white pool filter sand be soft enough to keep with them? White is my second choice if black is not going to work.

As for keeping two of them, I have seen videos on YouTube of more than one being kept successfully, even at larger sizes. I know that this is not the norm and if it ends up being a problem then I will separate them and find a new home for one of them. I want to try to have two and figured if I raise them both together from this very tiny size (I think they are probably siblings) and make sure they have plenty of room and hiding spots then I have the best chance of them getting along when older and larger. I know that it still may not work but I would still like to give it a go for now and find one a new home later, if needed.

As for the 220 gallon tank, my plan is to have it up and running within the next two to three months. I know that with proper care and diet these guys grow very fast. I swear I think they are already larger than when I got them two days ago. Lol

Fortunately, I have not had any trouble getting them to eat. I am using frozen bloodworms because that is what the LFS (Gerbers Tropical Fish in Dayton, OH) was feeding them. I will try to get them onto earthworms when they are a little bit bigger but any other food recommendations for them at this young age are more than welcome.

Thank you for all of your help!
 
Well, my ax refund came in. I am actively looking for an aquarium in my area. I am in search of an aquarium at least 220 gallons. I have one in my area but it is not a drilled tank (I would really prefer a drilled tank because I don't want to risk drilling it myself, but I will if I have to) and it only comes with a 2x4 stand that is unfinished. I really need a finished stand because it is going to be displayed in an open area. I did find somebody selling a 180 gallon stand but wanted to confirm that this stand will hold a 220. I know they have the same footprint but will the stand for the 180 hold the extra weight of the 220? I would really like to know because they are both priced low enough that I could probably jump on them and then just drill the tank myself.

I am thinking I will pick up a cheap 55 gallon tank and turn it into a sump for the tank and I plan on using a turnover rate of about 6x per hour. What do you all think about this?

Lastly, I will probably use white pool filter sand for the substrate. Does anybody know how much sand I will need to achieve about 2-3" thick on the bottom? I am planning on adding some plants but I really don't know which plants I will choose yet. I am very interested in dwarf hairgrass but I will have to check how compatible they will be.

Thank you all very much for your help. I am looking forward to getting this tank set up and running to get these fire eels into their new home.
 
Also, if anybody knows of a good deal on a tank that is 220 or larger in the Dayton, Cincinnati or Columbus, OH area, please let me know. My budget is around $500-700 for a plain tank and stand and closer to $900 for a tank complete with filtration.
 
Cant answer any of your questions except about the DHG (Dwarf Hair Grass)

Sadly, no DHG wont work unless you at minimum provide it with a nutrient rich soil and good lighting, not to mention your eels may dig it up...

I would go with larger plants that can be tied down such as Java Fernn, different Anubias or maybe even an Amazon sword...

-EDIT-

Here are two sample pics pulled off google of tanks using just anubias and wood as aquascaping...

Here are some pictures of my eels. They are still in my 29 because I'm still working on my 220 setup. They are around 7-8" now. One is much thicker than the other but they are close to the same length.
 
Yup, they grow pretty fast, I had mine in a 55 gallon until it was around a foot. Size of tank is less of an issue with eels than it is with other fish of similar length (eels can bend better than others). I will say you probably don't want to use plastic plants as they can scratch an eel. As others have said 2 of these may end up being more than you can handle (even in a 220). I did see one person with 2 on youtube, but I think their aquarium was like 360 gallons and the eels were not quite max size. My dream tank would have 4-5 fire eels with some bichirs, probably in the 600 gallon range. Good luck with your eels though, if you have come this far you are doing something right by them.
 
There are a few calculators online to help you work out how much substrate by the depth of substrate for the size of tank. If i come across one again I'll link it, otherwise google is your friend!

Food-wise you can cut in to strips things like prawn, fish, mussels. They often won't take it at first cos they're not familiar with it, so if you dip it in bloodworm juice and try hand feed them it they often start taking it and then learn to love it. I've had much success with this method so far.

I also have two fire eels in one tank. Be prepared for lots of people to say it's not advised. They're saying that because it's usually true. However, I rescued both mine and now I can't bear to choose between them and know it'd be difficult to find one of them a home of the standard I hope I can provide. Just do your best for them, that's all we can ever do for our pets. Provide plenty of hiding spaces and plants, keep them fed, and keep an eye on them. Some aggression is normal and natural, the hard part is knowing when it's going too far.

Btw tubes are great, I spent ages trying to find the right size for my littler eels. We found some black pond pump tubing from a garden centre. I'm sure similar must be available in the US?
