I'm really new to keeping fish, so please be patient.
I purchased a tank, for which i followed the (very vague and incomplete, so it turns out) guidelines for setting up, and 3 days later added a Betta. I know, I know, I should have cycled... BUT at the time I did not know this as I was told there was no point in trying to cycle a small tank (19L). Further research has obviously shown this to be untrue, but there is not much I can do about it now as I have no available cycled tank to house the poor little guy in in the meantime. Believe it or not I did do a lot of research about the fish, but silly me forgot to look up some on the tank... My bad, but we all make mistakes.
I have however ordered a testing kit since finding out this information, and intend on doing frequent 20% water changes.
Annnyway, the reason I am posting is because I have noticed that when my Betta goes by the intake of the filter his fins tend to get sucked up. He doesn't seem too bothered by this, and can wiggle free, but it gives me an uneasy feeling, so i would if possible like to 'baffle' it. The only problem is that i seem to have an odd filter.
I have attached a photo the tank I have (although it is not my tank in the photo), and if you see there are slits on the left hand side- well, they seem to be the intake, with the 'tap' like shape being the output on the other side (Betta does not seem too bothered by output with filter on lowest setting).
Could anyone offer any advice on whether i need, and would be able, to baffle the intake?
Also, I don't know if maybe anyone could offer any advice on what type of filter this is? It uses a combination of black and blue sponges and carbon and ceramic mesh bags. And is it safe for me to leave it on the lowest setting?
Thanks again for any help :)
