More pics from 1800 gal, lineatus and the big red fin flagtail (its tail was badly damaged by a tig tank mate when it was 5", almost all of it fell off afterwards and the new one that grew in its place has never been as spectacular as the original should have been, my feeling is, anyway...):
However, lineatus is a nasty tank mate and has earned a one way ticket back into one of the 240 gal. This is what it had done to one of the 14" snail bullhead tank mates over a couple of months period by supposedly sucking on one spot over and over and over again, it was unsettling, I thought maybe it was a disease and I couldn't catch the culprit... until I finally saw who had been doing it - lineatus!
It started out as a small dot and kept growing and growing into this crater. In general, I find Ictaluridae to be rather strange in this regard - bullheads and channels let tank mates such as Labeo, pacu, and now striped prochilod suck on them and bite them as they please...)
