So, after reading through several threads and watching plenty of youtube videos for common pieces of advice I haven't seen much on keeping rainbows with female bettas.
I only have one rainbow after I sold all my fish and I do plan to get maybe 3-4 more m/f pairs. But at these rate I feel like my tank is going to be overcrowded. Anyway back on topic.
I have a 40 gallon tank that needs help desperately. With a pH literally off the charts due to my softened well water I need to make quiet a few adjustments before actually planted my tank and adding fish.
I've been told that 11 female bettas should comfortably live with 8-10 purple passion danios of which I have two.
So with these future plans I have 19-21 fish just in danios and bettas. I live like this is a tad bit over kill considering I want to get 2-4 inch rainbows and already own 3 violetta corys and 2 rubber lip pelcos.
I'm so far a bit wary on the whole rainbow concept as there is little information. My male betta goes after my last one because he is injured and alone. Of course my betta has his own tank but I put him in mine for 2-4 hours at a time to test his aggressiveness and the nipping of the current fast swimmers. Of course I can't be 100% sure if my rainbow and danios are not fin nippers but tests with continue as changes are made with fish and tank alike.
So here's what I've gathered so far:
~~~~~~CURRENT TANK PLANS~~~~~~
-Do a filter check since it hasn't been running as fast -.-
-Update light to a 36" TH50 for exceptional growth of plants.
-Add homemade Co2 system (yeast, sugar, 2 liter bottle, etc.)
-Create non-toxic lightweight rocks either from pumice or Tetra pond foam sealant -here-
(I will have to carve it -.-)
-Create new theme with a heavily planted tank and natural viewing for fish to feel natural while being observed. The tank will have an easy moveable layout so catching fish is easier.
~~~~~~BONUCY FISH PLANS~~~~~~
- Buy 8-12 female bettas separately to observe their temperament.
- Buy 6-8 more purple passion danios. (Most likely 6)
- Buy 3 more pairs of three different rainbow fish (7 or 6 rainbows)
- Buy one more school of pygmy corys.
- Possible additions according to temperament, space, crowding, or problems.
-Tank has a pH above 9 regularly, hard on the fish and plants.
-Lights are fluorescent.
-Rainbow and danios are currently NOT fin nippers (this can change).
-My male betta is currently too aggressive to be let loose regularly.
-Tank is almost a year old.
So here are my questions for you fish and betta experts :3
Are rainbow fish compatible with male or female betta(s)?
At the current plans above what would expert fishkeepers recommend for a 40 gallon tank?
More questions will be asked as I progress with my research.
