He's 9-11 inches is he a true tyre track eel he's growing pretty big I got him 4mnths ago at 5inches now he's bigger I feed him feeder guppies once a month and blood worms with market shrimp daily?
here's another pic
I got him about 3mnths ago at 5 inches now he's 8 maybe 10???
Looks like a true TT.. the larger species as well...instead of guppies you may want to try nightcrawlers.. my TT once it got larger started trying ot eat his tank-mates.... and they will get big.
I know it's a moot point now ( atm I'm 34 weeks pregnant so I don't check MFK daily lol) But nightcrawlers are very good for both Bichir and spiney eels in general.. The nutritional content is much better then frozen bloodworms are, and great once they outgrow live black worms ( another high nutritional food) I've found both these foods much better for my bottom feeders, it puts on a healther weight gain as well as length to my fish. The downside is being live foods some fish don't transfer onto pellest as easy as dead ones... and nightcrawlers aren't very easy to feed dead, the only application I've found that works is a home-made gel food ( alot of info in the ray subforum about members useing home-made for their worm loveing rays) but I've personally found it more of a pain to go that route then just keep them on the worms. Some people have success, particularly with very young spineys in xfering them onto pellets.. I've not been so lucky.. atm 2 doz nightcrawlers cost me $3.50 at Cabelas and lasts appox 2 -3 weeks feeding 2 M dayi in the 10-16" range. I found with bloodworms and frozen krill I needed to feed them daily to keep them in good size, while now every other day or 3rd day seems sufficent.
as for Bichir.. my sens and ornate loved the nightcrawlers and would deathroll larger peices.. It was one of their favorite treats. and over-all ime alot less messy then bloodworms.
I do keep bloodworms and krill in my freezer in case I can't get out to get worms ect, or someons is watching them and won't feed them worms ( my mom absolutely refuses to cut up worms, but will break up peices of bloodworms.) and imo it's not bad to try and give them as varied a diet. some people feed their larger spiney eels tilapia.. I don't eat the stuff.. and avoid farm-raised fish because of the mercury content. But most fresh seafood is worth a shot at trying, in the middle of wisconsin it's hard and expensive to find good fresh seafood... Cali might be abit easier
