I have a pair of Bristlenose plecos, one male called Treeface (cruel I know) and a female. They are just over a year old and two days ago I noticed 30 odd eggs stuck to the glass with Treeface protecting them. They were all orange in colour, but gradually over the last few days they have turned colourless and disintergrated! Now I have none left. Have they all died or have they spawned and then been eaten? Im very confused
