Hi My Betta has a funny lump on his side and I'm not sure what it is. I have taken a pic with my mobile but it's not very clear and I can't upload pics from the proper camera til tomorrow.
He is in a 4 gallon tank on his own and water stats are ammonia 0, nitrite 0 and nitrate 30. I change about 30% water every week. I have had him for about 4 months and he is fine and nothing has changed in the tank.
I check him properly every day when I feed him and he is so nosy he is out and about all the time watching what's going on around him so I see him all the time. I didn't notice the lump until this evening though so either it was very small yesterday and I didn't notice it or it appeared quickly today.
He has been constipated before but it didn't look like this as the lump is vey pronounced (small pea size) and ONLY on one side of his body. I am bit bothered because it is so pronounced the scales on it seem to be standing up and I know what that means..... He's not doing anthing else different though and is behaving absolutely normally and there is no sign of strange poo. I am going to feed him a pea now just in case but has anyone got any ideas in case it doesn't help?
Thanks
Fingers crossed it might do something... Any recommendations for which one? I'll go to Maidenhead Aquatics (am in UK) tomorrow to get whatever I can. God, it seems to be the week for it - we lost one family cat last week to a bump we think and another (15 yr old) is looking really poorly at the moment.
