We have a brand new 200l tank (Cycled) and stocked it for the first time on Wednesday, this consisted of 12 neon tetra, 2 dwarf gourami and 3 Otos.
Today I tried to move one of the Otos into my Betta's little tank to try and keep the plant clean (my Betta is rather anti-social and ate the 3 neons I tried to put in with him before so I kept a close watch and had to removed the Oto after about 2 minutes
Two of the larger Otos began chasing each other all over the place soon after (I dont know if one of them is the one I tried to move or not) they didnt make any effort to hide from one another even though there is plenty of space and hiding places.
I googled it because its stressing the Gourami out and it appears that its a breeding behavior and that its rare for them to breed?
I didnt even think they were fully grown as the fish you buy from stores are usually young and they are not 3.5cm long yet.
What do I do now? there is plenty of brown algae (diatoms) in there at the moment, should I supplement their diet? We plan on getting Cory Catfish in a few weeks so we will probably need to supplement then anyway.
What about any eggs or baby fish that come along? should we not put anymore fish in there for a while? Was really not expecting to face this problem so soon!
Thanks for any help!
