Hello everyone, I'm a fairly new lungfish owner and was wondering if you guys could help me identify something. I've had my West African lungfish for almost a year, he's about 10" long and pretty active. In the last few months I've noticed he's developed a black spot or blotch on his belly - maybe 0.5cm. I haven't observed any behavior changes - he eats consistently and eagerly, and is as active as ever. The spot doesn't seem raised or sunken.
I think the spot is slowly growing though, and was wondering if anyone knows what might be the cause. It doesn't match his coloration/spot pattern - I'll try to post some pics if the forum lets me (this is my first post).
Tank specs:
20 gallon (I know this is very small, but it's only temporary, I'm currently getting a bigger one. He's only 10" right now)
Temp: ~80F
pH: ~7.5
ammonia, nitrite: 0ppm
nitrate: ~10ppm
Penn Plax cascade 1000 filter, with filter floss and sea chem matrix biomedia
The tank has sand substrate, some java ferns, and some driftwood.
