Good-by Gibby!

English:
Sad day. Last night, soon after introduction of new fishes, my Gibby was normal as usual, but then started acting very strange. First he layed on his belly and stopped sucking glass and driftwood, and only when I touched him he would again swam to the glass like before, alas, not for long. Today he finally layed on the buttom motionless.

I can only put few theories why this happend. Either he ate too much algae or something bad (his belly was a bit round) or some bacteria overtook his imune system. He had some strange white area on his back, so this could be true. I did partial water change and some cleaning (no food this evening) and will closely observe other fishes next few days.

Srpski:
Tužan dan. Sinoć, ubrzo nakon ubacivanja novih ribica, Gibby se ponašao normalno, ali je nakon par sati počeo da se ponaša vrlo čudno. Okrenuo se na leđa i prestao da usisava alge sa stakla i panja, a tek kada bih ga dodirnuo okrenuo bi se i ponašao normalno, ali ne za dugo. Danas sam ga pronašao nepokrernog na dnu.

Mogu samo pretpostaviti zbog čega se ovo dogodilo. Ili se prejeo algi ili je pojeo nešto loše ili su ga napale neke bakterije kada mu je opao imuni sistem nakon transfera. Imao je nešto čudno belo na leđima iznad glave. Izmenio sam deo vode i malo sredio higijenu akvarijuma (nema hrane večeras) i pomno ću pratiti dalji razvoj događaja.
