Help Betta with tiny hole on tail

Hi

I need some help. Has someone experienced something similar with his/her Betta fish? Yesterday I noticed a tiny hole onmy betta fish tail (Pictures attached). He has been feeding well and he is active. He also has been making bubble nests (pic attached) this makes me think that he is healthy. I don't know if this hole might be the start of fin rot or not. Has someone experienced something similar? Is this fin rot or something else? I have 6 Rummy nose tetras in the same fish tank (30 litres). Tank has been running now for 4 months. Water tests are alright.

 

Hi, that doesn't look like finrot to me, it's starts at the edges generally and causes discolouration. It is almost certainly a nip - bettas will nip their own fins when stressed and tetras are often fin nippers. 30 litres is fine for a single male betta but nowhere near enough room for the rummynose tetras. I would put them in a community tank if you have one or re-home them if not. I don't mean to sound harsh but this is simply not enough room for all of those fish or really for any apart from a single betta and I'm fairly certain some nipping has occurred. Your betta will be happier in there on his own or with a snail or maybe some shrimp if he doesn't eat them and the tetras need at least 60 litres, really more like 100 litres or more to be honest.

Thank you! I feel relieved knowing that it is unlikely to be fin rot. I will be trying to find a solution for my tetras

 

Awesome, sorry to be bearer of bad news on stocking but they will all be much happier going forward. Your betta looks really healthy, if it gets worse or looks dicoloured check back but I think he's fine an it's just nipping. Indian almond leaves are great to prevent and to some degree to treat fin rot and other ailments as well as reducing stress and stabilising ph. I actually boil them a little to release tannins which colours the water, my lot love it! Putting some taller or floating plants in or one of those floating logs or suction hammocks will help to as they breathe air and rest at the surface. LOADS of plants are ideal lol looking good so far though

Now I have an excuse to set up my third fish tank. It is always exciting to do it. Thanks for all the tips. They are certainly very helpful. I didnt know about the Idian almond leaves.

 

That's the spirit! I set up a second freshwater tank as the male plecs re-homed with me needed to be separated lol. The almond leaves are brilliant, most freshwater tropical fish benefit from them as many like soft, acidic water. the exceptions are livebearers like guppies, mollies, platys, etc. Most other commonly kept fish like tetras, dwarf cichlids, corys, gouramis, etc love tannin water.
