They look like Cory eggs to me. Looks to be the right color/shape, and most cories lay their eggs onto an available flat surface, where they stick; although they often lay eggs as they're swimming, and therefore are often found in scattered lines, not clumps. Ancistrus and most other Loricariid species also spawn after an influx of colder water, but their eggs are typically slightly larger and they do exhibit parental care, plus they tend to lay eggs in some sort of enclosed area- can be anything from clay breeding caves to the space between a HOB filter and the tank walls. They don't look like tetra eggs, but seeing as I've never bred tetras, I can't be sure. When transferring eggs, make sure the tank has stable parameters and some decent flow; or else they won't develop properly, or so I'm told. If they are cories, the newly-hatched cories do need to be situated onto some sort of microfood; I typically use f/t baby brine shrimp. From the picture, I'm not completely sure if they're fertilized; they may not necessarily be viable.
