Fire eel tankmates

[Bret11]

Best tankmates for a 15 inch fire eel and a 9 inch black ghost knife in a 125 gallon tank.

Tank will already be overstocked with those two fish. The fire eel can reach up to 40” and I know the BGK can reach a pretty large size. Truly, that tank is too small for the fire eel, but I’m not as familiar with the BGK.

I know. I am planning to get a 250 gallon in the future but what would be good with them for now.

I’d recommend you wait until you upgrade. That fire eel will be 24” before you know it.

Ok. What if I got a fire eel that was 9-10 inches with the 9 inch black ghost knife. Would that be better.

It will still only take the fire eel less than a year to be pushing 18-24”, so unless you plan on upgrading in the next six months, I recommend you hold off on getting another fish.

I will say that with enough water changes, you might get away with adding another fish, but we are talking around a 90% water change at least once a week, maybe twice, and then depending on the type of filter, it may need cleaned out once a week.

I have a medium BGK and a black spotted eel, along with more, in a 150 and I'm doing 75% changes 2x a week to keep things in check. Don't push it with the 125g where it becomes too much of a chore for upkeep where you slowly stop.
